I’m looking for a freelancer who can help me perform SW updates to the Automotive Audio Amplifier. The parts are not in the vehicle and are located in El Paso.

I need someone to install and fully configure the latest stable release of MySQL on a Windows-based machine that will act only as a local development server. Your job starts with the clean installation itself—downloading the correct installer, choosing the right configuration options for a single-instance environment, and making sure the service starts automatically with Windows. Once the database engine is in place, please secure it by setting a strong root password, removing test databases, and enabling any recommended Windows firewall rules so it is not exposed beyond the host PC. I will also need one non-root user created with full privileges for development purposes, plus a short verification script or command-line check that confirms connections work from MySQL Workbench and ...
Upgrade server 2012 essentials to server 2022
I’m on Windows 11 and want Microsoft OneDrive completely gone—no lingering background services or registry traces. Once it is uninstalled and the sync folders are safely disconnected, I need a thorough audit of my C: drive. The goal is to identify and eliminate every duplicate across documents, photos, videos and any other file types, then reorganise what remains into a clearer folder structure. I’d like sensible, easy-to-navigate directories (e.g., Work, Personal, Media) and shortcuts updated so existing programs still find what they need. Please back up anything you delete or move, provide a log of duplicates removed, and deliver a concise before/after folder map so I can see exactly what changed. Tools such as PowerShell, WinMerge, dupeGuru, or comparable Windows 11 ...
I need a Windows-focused developer who can turn XMRig into a background service for a fleet of mining PCs I already operate. The goal is simple: once the installer runs, XMRig should install the rig with the needed program, start automatically with the OS, and apply my custom CPU tuning without any visible console or tray icon. Key details • Target OS: Windows 10/11 on consumer-grade hardware • Required tweak: XMRig custom setup as it runs (no GPU work) • One-click or fully installer preferred (Inno, NSIS, or your tool of choice) Deliverables 1. Compiled XMRig binary with my CPU config baked in (or an editable JSON if you have a smarter approach) 2. installer/script that registers the miner as a background service and confirms successful launch 3. Brief usage:...

I host my foundation’s domain with Hostinger and have just discovered that they no longer offer email services. I need a professional who can quickly step in, create more than 10 branded mailboxes, and point everything to my existing Google Workspace tenant. The scope is straightforward yet detail-critical: • Create the new user accounts on Google Workspace under my domain. • Update all Hostinger DNS records (MX, SPF, DKIM, DMARC) so mail flows smoothly to Google. • Verify that Calendar integration, shared mailboxes and advanced security settings are all active and tested for every new user. • Supply a concise hand-off document showing each change made and how to add future accounts.

I’m looking for a reliable local technician who can act as the hands-and-eyes extension of our remote IT team whenever a workstation issue crops up. The core of the role is simple: be on site, follow the real-time guidance of our engineers, and help us troubleshoot whatever is affecting the user’s desktop or laptop. Typical calls may involve tracing connectivity problems, reseating or replacing components, checking cabling, or running through software prompts that our remote tools can’t reach because the machine is unresponsive. While the immediate need centers on workstation troubleshooting, a bit of flexibility is appreciated—occasionally we might ask you to press the power button on a switch or confirm a status light on nearby gear if you’re already ther...

I need a dependable technician who can take over my helpdesk queue during the overnight shift (roughly 11 p.m.–7 a.m. UTC). You will be the first point of contact for any Windows-based incidents that arrive after hours and will keep the environment stable until the day team comes back online. Your nightly workflow will revolve around three core areas: • Troubleshoot incoming tickets that relate to hardware faults, software errors, or sudden network disruptions. Clear, concise ticket notes are mandatory so the day shift can see exactly what you did and why it worked. • Apply scheduled operating-system and application updates that have been pre-approved in our change calendar. Each update must follow the documented rollback procedure in case of failure. • Perform rou...
I’m midway through a project and need to get robust monitors in place on Datadog. While I’m comfortable with the application stack itself, my Datadog knowledge is minimal, so I’d like an expert to take ownership of the monitoring layer. Scope • Analyse the current environment (mix of EC2 instances, Docker containers and a couple of managed services) and translate our reliability goals into actionable Datadog monitors. • Configure the monitors directly in our Datadog account—thresholds, alert conditions, notification channels, tags, dashboards, everything required for clear, noise-free alerts. • Walk me through the reasoning behind each monitor so I can maintain them afterwards. Short Loom recordings or concise written notes are perfect. Delive...

I have a clean Linux-based VPS and I need n8n installed from scratch, secured, and running as a background service. Once it is live, create a reusable n8n workflow that accepts a CSV file, parses its rows, and inserts nearly every column into an existing (or newly generated) MySQL table. If a field ever needs to be skipped, I want the mapping simple enough that I can toggle columns on or off later without touching code. Please include concise, step-by-step documentation for two areas: 1) Server side – every command and config change you run to install n8n on Linux, set up environment variables, reverse proxy (if used), HTTPS, and auto-start on reboot. 2) Workflow – screenshots or export JSON plus a plain-language walkthrough that shows where the CSV is read, how the colu...
I need someone who can make all Windows TPM 2.0 remote attestation checks pass inside a Linux KVM/QEMU Windows VM. I don't care how it is implemented. I just need a working setup where everything passes, including: Trusted vendor EK/EKCert EK certificate verification EK public key matching the certificate AIK enrollment and trust Isolated VM PCR domain TCG Event Log PcrsMatchTcgLog=true PCR replay / all PCRs matching TPM Quote verification Nonce verification Credential Activation Microsoft/external EK verification Windows TPM pre-attestation / health checks Current setups only give me part of this: physical TPM passthrough gives trusted EK/EKCert but causes PCR/TCG log mismatch, while software vTPM gives clean isolated PCRs but uses an untrusted/operator EK certificate....

I have roughly 1,000 user IDs that must be reviewed and cleaned up today. You will connect to my Windows PC via remote desktop—this is my first time granting remote access, so reliability and care are key. Using only the standard tools already on the machine, you’ll open each account, check the list of active devices, and revoke every extra session so that just one device remains. I’ll demonstrate the exact steps before we begin; after that it’s a repetitive but precision-focused task that has to be finished before the day ends. When you message me, let me know: • the earliest time you can start today, • how long you expect to take for the full batch, • your total fee, • any comparable account-maintenance or data-entry work you’ve handle...
