My production app runs on PHP 7.4 with CodeIgniter 3. A few weeks ago—right after moving the server from E2E to DigitalOcean—it began going down like clockwork at 11:30 AM and again at 7:00 PM. No code changes were involved; only the hosting environment shifted. I need a careful investigation that starts with server logs (web server, PHP-FPM, system, MySQL) and includes cron jobs, resource spikes, firewall rules, and anything else that could trigger those time-bound failures. Once you isolate the culprit, apply or outline a fix, then monitor long enough to confirm the application stays online through at least one full cycle. Deliverables: • Concise report showing the root cause with supporting log excerpts • Implemented (or clearly documented) remedy • Proo...

My team manages a mid-sized data center that runs almost entirely on Cisco switches, routers, and firewalls. I need an experienced network engineer to jump in on a contract basis and keep everything running smoothly. Day-to-day work revolves around classic routing & switching tasks—think VLAN design, trunking, OSPF and basic BGP tuning, plus the inevitable “why can’t that server talk to that subnet?” moments. The core stack is Cisco IOS/IOS-XE with a mix of Catalyst and ISR hardware. Because this installation underpins production workloads, fast-paced troubleshooting is as important as clean architecture. You should be fully at home with TCP/IP and the OSI model, comfortable tracing packets through multiple hops, and ready to document changes clearly for hand...

Our real-time chat application has become unstable across both the User and Admin portals. The issue appears most clearly when sending messages. Core business logic has not changed, so we suspect a problem in asynchronous message handling or the caching layer, such as a race condition, stale cache, invalidation issue, or concurrency gap. We are not certain whether there were recent hosting or infrastructure changes. What you will do - Trace the message sending flow end to end, focusing on async orchestration and cache interactions - Use logs, breakpoints, or profiling tools such as Redis monitor, Node.js inspector, or equivalent - Identify and confirm the root cause with clear technical evidence - Apply and commit a small, safe fix if possible (for example await misuse, cache invalidation...

I run a live production app that combines a .NET 8 microservice back-end with a React Native front end, hosted on Ubuntu servers in AWS. Right now the most urgent need is to deliver new functionality, and nearly all of that work sits squarely on the back end. Your first assignments will centre on extending our microservice architecture and exposing new, well-documented APIs. You’ll be writing C#, containerising services, wiring events through RabbitMQ, and persisting data in PostgreSQL—then shipping the code straight into production. I pay $6/hour for hands-on development only; time spent reading code, researching, or experimenting is on the freelancer. Work independently, own your tasks, communicate clearly, and suggest improvements when you see them. Do that well and there&r...

I need a Dynatrace-driven, end-to-end observability framework rolled out across several AWS-hosted microservices. The goal is to move from scattered point checks to a single, actionable view that covers infrastructure, runtimes, and user-facing performance. Scope • Instrument every workload that lives on AWS—EC2 instances, container clusters, Lambdas, managed databases, you name it—so that Dynatrace captures golden signals automatically. • Create service topology maps that make call chains and dependencies obvious at a glance. • Design production-ready dashboards focused on CPU / memory usage, response times, and error rates; the layout must let engineers trace an issue from high-level SLO status straight down to the offending log line. • Define pra...

I run a Laravel-based site that relies on Tiny File Manager for everyday media tasks. The file-manager endpoint has suddenly stopped responding—requests to /filemanager/connector just spin until they time out—while the rest of the application works fine. I need someone who knows both Laravel routing/middleware and Tiny File Manager inside out to trace the root cause and restore full functionality. What I already know • The problem is isolated to the Tiny File Manager module; other APIs are healthy. • No recent composer or npm updates were made before the failure. • Server is Ubuntu with Nginx and PHP-FPM; SSH access and a staging branch are ready for you. Your task • Identify why the endpoint is unresponsive (routing clash, permission issue, missin...

We are spinning up a green-field serverless stack and need three seasoned Python engineers to take the lead. Everything will be built from scratch, so you will shape the architecture as well as the codebase. The immediate milestones involve: • Designing and coding AWS Lambda functions that expose REST-style endpoints (API Gateway) and integrate cleanly with other AWS services. • Crafting automation scripts—also in Lambda—so deployments, scheduled jobs, and housekeeping run hands-free. Production-ready quality, test coverage, and clean, modular code are essential because these functions will sit at the core of our platform. If you are comfortable making technical decisions, writing idiomatic Python 3.x, and navigating AWS tooling with confidence, this work will sui...

I already have GNU Octave installed on an Ubuntu 20.04 box, but the configuration isn’t finished and I don’t have the time—or the depth of expertise—to chase every dependency and service tweak myself. The goal is to get the server fully operational and then show my team how to use it with confidence. What I need from you: • Finish the Octave Server configuration so it starts cleanly at boot, is reachable over the network, and behaves the same for every session. • Create a few custom user roles with the right permission levels. • Recommend (and install if approved) any additional open-source tools that logically complement Octave. • Host a 1 hour Zoom call where you walk the team through connecting, running code, and general workflow ti...

I need my current Prestashop 1.6 store moved to Prestashop 8 without losing any business-critical data. The migration must include: • Every order, customer record, and address • All product information, variations, attribute sets, and combinations • Every image, attachment, and file reference linked correctly in the new catalog Please keep URL structures, tax settings, and stock levels intact so the new site continues to run seamlessly once DNS is switched. I will supply full server access for both the source and target environments and can pause live orders during the final cut-over window you specify. Testing on a staging copy, validating totals, and fixing any integrity errors before going live will be part of the scope. If you have proven experience upgrading la...

I’m ready to purchase a Linux VPS that already has root access, SSH enabled, and—most critically—port 25 fully open so I can begin configuring an email server right away. The operating system must be Ubuntu. I will handle most of the administration myself, but I’d like the option to reach out for occasional guidance if something falls outside my expertise. If you can provision such a server immediately, please let me know the specs, datacenter location, and hand-over timeline. Credentials for both the root account and a secure console (or any control panel you include) should be provided upon delivery, and port 25 must be verifiably unblocked before transfer.

I run a small Asterisk lab and I need to run controlled test calls where the caller ID can be set to any value I choose. The goal is strictly testing and development, so everything must remain inside a legal, closed-loop environment. Here is what I need from you: • Configure or show me how to configure my existing Asterisk 18 instance so I can present arbitrary caller IDs on outbound calls. • Supply any dial-plan snippets, AGI scripts, or CLI commands required, along with clear commentary so I understand why each line is there. • Recommend a SIP trunk or gateway configuration that reliably passes the spoofed CLI without rewriting it (I am open to using my current trunk or switching to one you suggest). • Walk me through a short live demo—screen-share or re...

My website has suddenly stopped opening altogether. Instead of loading the homepage, every browser simply displays “Try: Checking the connection – ERR_NAME_NOT_RESOLVED.” No 404 or 500 screen appears, so I’m assuming this is a DNS or hosting-level problem rather than an in-app bug, but I need an expert to confirm, trace the root cause, and get the site back online. Here’s what I can share right now: • The symptom is just that single ERR_NAME_NOT_RESOLVED message—no other error pages. • I haven’t changed code, design, or plugins recently, so the break is likely server-side (DNS records, SSL, nameservers, firewall, or similar). • I still have full access to the domain registrar, cPanel / hosting dashboard, and SSH if you need it. Wha...

My WordPress site feels sluggish and I want visitors to enjoy a fast, seamless experience on every page—from the homepage through to checkout. I need a specialist who can investigate what’s holding the site back, put the right optim-speed tactics in place, and verify that those changes genuinely cut load times. Key deliverables • Full performance audit (core web vitals, server response, plugin/theme impact) • Implementation of best-practice fixes: caching, image & asset compression, code minification, database cleanup, and any server-level tweaks you deem necessary • Before-and-after reports showing measurable improvement (ideally sub-2-second first-contentful paint on desktop and mobile) I’m open to recommendations on tools—WP Rocket, Lit...

I’m spinning up a brand-new AWS environment and want it built right the first time. The core stack must include secure EC2 instances running a database server workload, S3 buckets for object storage, and at least one RDS database instance. This deployment will host banking-related data, so tight network segmentation, encryption at rest and in transit, and granular IAM policies are mandatory. My preference is to have everything created with infrastructure-as-code (CloudFormation or Terraform) to keep future changes controlled and auditable, but I’m open to your recommended tooling if it speeds delivery without sacrificing reliability. Deliverables • VPC design and implementation with public/private subnets, route tables, NAT, and security groups suitable for a production ...

I have a Python script that relies on Telethon to verify whether a phone number is linked to a Telegram account. In its current state the success rate is frustratingly low—numbers that I know are active on Telegram are repeatedly flagged as “no account”. My own diagnostics are limited: logging and error-handling are only partially implemented, so I’m still guessing whether the root cause is rate-limiting, subtle response-parsing mistakes, or intermittent network hiccups. What I need, quickly, is a rock-solid solution that: • Accurately detects the presence of a Telegram account for both domestic and international numbers. • Includes clear, structured logging so I can trace every request/response cycle and spot any future anomalies without extra codin...

My home Wi-Fi was recently breached and I can still see unfamiliar devices connecting even after I changed the password. I need an experienced network-security freelancer who can jump in remotely, pinpoint how the unauthorized access is happening, and lock the network down for good. Here’s what I expect: • Run a quick audit of my existing router settings, logs, and connected clients to confirm the intrusion vectors. • Reconfigure the router with stronger protections—WPA3 where available, hidden SSID if practical, MAC filtering, upgraded firewall rules, and a properly segmented guest network. • Verify and, if necessary, update firmware, disable insecure services (WPS, UPnP, weak remote-admin ports), and adjust DNS or VPN settings to shield traffic. •...

I’m setting up a new Survival-only Minecraft world and want it ready to welcome roughly 50-100 players without lag or downtime. Your task is to stand up the server, harden its performance and load in the exact plugins I’ll share once we begin (economy, land-claim, anti-cheat and a few quality-of-life extras). A Paper or other high-performance Spigot fork is preferred, so please configure the JVM flags, view-distance and garbage collection settings that keep the tick rate stable even during peak hours. After installing the plugins, sort out their dependencies, tune every config file, and run stress tests to be sure permissions and features behave as expected. Deliverables • A live, fully configured Survival server running the latest Paper/Spigot build • All r...

I have a functioning web application that now needs two key upgrades: • File attachments must be securely uploaded and stored on Cloudflare. The flow should support direct-to-Cloudflare uploads so the files never touch my server, and return the public/private URLs to the frontend. • Google-based Single Sign-On has to be woven into the existing auth layer so users can log in with their Google accounts across both QA and Production environments. You’ll work in my Git repo, create the necessary Cloudflare bucket (or R2) configuration, wire up the upload endpoint, and finish with a clean README that lets me reproduce the setup in staging and prod. My stack is a typical React frontend with a Node/Express API, so please be comfortable with that toolset and common helpers like ...

I need hands-on, day-to-day help from a seasoned DevOps Engineer to keep our AWS environment running smoothly while we roll out new features. The immediate focus is on three pillars: building a reliable CI/CD pipeline, codifying our infrastructure, and tightening monitoring and logging so issues surface before our users ever notice. We host everything in AWS, so you should feel at home with services such as CodePipeline, CodeBuild, CloudFormation or Terraform, ECS/EKS, CloudWatch, and any complementary tools you prefer (Jenkins, GitLab CI, Prometheus, Grafana, ELK, etc.). While DevOps work is priority one, experience touching data-engineering workflows or handling database administration will be an advantage as those needs crop up after the core automation is stable. Deliverables I&rsquo...

My Hostinger VPS was automatically shut down after malware activity was detected. It runs on Linux and already has basic antivirus software in place, yet something slipped through. I have not been able to pinpoint any suspicious files or processes so far, so the machine will need a full forensic sweep before it is brought back online. Here’s what I need, step-by-step: • Power the VPS up safely through hPanel or SSH rescue mode and capture a snapshot for analysis. • Audit every running service, scheduled task, and startup script, identifying and terminating malicious or unnecessary processes. • Locate, isolate, and delete infected files or code injections (web roots, crontabs, tmp folders, hidden binaries, etc.). • Patch vulnerabilities and harden the syst...

I run several call-center deployments on Vicidial 2.14 and need a senior-level hand to keep everything humming. Day-to-day work ranges from setting up and configuring Vicidial for new campaigns, maintaining and troubleshooting existing clusters when agents hit snags, to developing custom features or scripts that extend core functionality. Performance optimization will be your most frequent touch-point with me, so deep knowledge of dial-plan tuning, MySQL query profiling, and carrier-side fine-tuning is essential. All work is remote, ticket-based, and ongoing: sometimes a quick patch, other times a full rollout on fresh hardware. When a task lands, I’ll provide SSH or VPN access, the specific goal, and the expected turnaround. Clean documentation of what you changed and why is requir...

My MERN stack application is ready for production and I need it running smoothly on an AlmaLinux server. You’ll start with a clean box that currently has only SSH access; no Node.js, MongoDB, or build tools are installed yet. I do want help setting up that entire environment, so plan on installing the required versions of Node, npm/yarn, MongoDB and any supporting packages. Apache is the preferred web server. Please configure it as a reverse proxy so the React front-end and Express API are both reachable under the same domain, served over HTTPS with a free Let’s Encrypt certificate. If you like using PM2 or a similar process manager to keep the Node processes alive, that’s fine—just document what you do. Deliverables: • Deployed, publicly accessible MERN ap...

I need a small, self-contained Python script that logs in to Telegram Web with Selenium or Playwright, opens a given group or channel, and reliably pulls back the information No broader “bot-style” automation is required—just open, read, return the data, and quit cleanly. Please structure the code so the target link or @handle can be passed in as an argument and the results are printed or written to JSON; I’ll handle any further processing on my side. You’re free to choose Selenium or Playwright, but the solution must: • run on Python 3.x in a head Linux environment • respect Telegram’s login flow (QR / code) without hard-coding cookies • be well-commented so I can tweak selectors later if Telegram updates its DOM If you&rsqu...

I have four live WooCommerce stores that I’m ready to move off their current shared environment and onto a lean-cost VPS. I already have the new server provisioned; what I need is someone who can handle the entire migration end-to-end, keep downtime close to zero, and then lock the new box down with solid security hardening.

My AI Bot should be listening in the call, but i only hear a sharp noise 4. I know this is due to mis-samp...

I need a reliable specialist to help me squeeze more speed out of my Google Android Go phone. System-level apps—especially Settings and Camera—open sluggishly, and overall responsiveness feels capped. I’ll supply every relevant detail about the device once we start; what I’m missing is the technical finesse to upgrade or tune it safely and transparently. My research led me to the Firebase Go Admin SDK v4 migration guide, which emphasises trust, clean code, and zero shady shortcuts. I want that same ethos applied here: no questionable rooting, no data grabs, full accountability. Here’s what I’m after: • Diagnose current build and pinpoint performance bottlenecks in the OS layer. • Recommend or apply the safest OTA update, micro-GAPPS packa...

I need a seasoned Python programmer who can step into an in-progress data-processing pipeline and finish the execution work without altering the architecture already in place. The core logic—written in Python and heavily reliant on pandas—will be provided once we have an NDA in place. Your tasks are straightforward but must be carried out with precision: • Ingest several CSV files on a Linux environment, run them through our existing custom business-rule validations, and flag any exceptions exactly as the current specification dictates. • Attach pre-generated assets (primarily images) to each validated record. The mapping logic is already written; you will ensure it runs reliably across all edge cases. • Output a clean, well-formatted Excel workbook that mi...

I need a compact, reliable vision script for a roadside Raspberry Pi that spots any passing vehicle and immediately drives one GPIO pin high so a connected LED glows solid for a preset time, then turns off until the next detection. Key context • Location: mounted outdoors at curbside, so daylight changes, headlights at night, and occasional rain or dust are all realities. • Target class: vehicles only—cars, trucks, motorbikes.
