El objetivo es reducir tiempos, errores y costes en actividades como registro de órdenes, control de inventario, generación de reportes internos, gestión de turnos y procesos básicos de personal (altas, bajas, seguimiento de vacaciones y comunicaciones internas). Necesito una solución que se integre sin fricciones con el software que ya utilizamos; busco algo modular, capaz de crecer a medida que surjan nuevos requerimientos. Valoro especialmente arquitecturas basadas en APIs y microservicios, el uso de modelos de lenguaje (LLM) para toma de decisiones simples, y ...
I need a seasoned Informatica PowerCenter developer to dig into our existing repository, read each mapping from source to target, and surface the complete field-level lineage. The goal is strict data lineage transparency—every column, every hop, every transformation—so auditors and downstream teams can quickly verify how a value is derived. Here is what the engagement looks like: • Analyse all PowerCenter mappings, sessions, and workflows, including any reusable mapplets. • Parse XML exports or query repository metadata directly; whichever approach you prefer, as long as it captures every transformation rule accurately. • Produce an Excel workbook that clearly lists source fields, intermediate transformation steps, and final target fields. • Compleme...
I need a developer who can build a lightweight API-level plugin that takes the personal information from our existing manual entry forms and pushes it directly into the patient-record module of eClinicalWorks. The goal is to eliminate hand-keying while keeping every step HIPAA compliant and fully auditable. Here is how I picture the workflow: data is captured from the forms, parsed, mapped to the correct eCW patient fields, then validated and submitted through the eCW API. The plugin should return clear success or error messages so my staff immediately knows whether a record was created, updated, or needs attention. Robust field-mapping logic, input sanitation, and rollback on failure are essential. Deliverables • A compiled, installable plugin (or microservice) that connects to t...
I need a production-ready dashboard built in SAP Analytics Cloud that pulls live data from our SAP HANA system. In addition, the design should allow me to enrich those HANA figures with supplementary feeds coming from a couple of REST APIs and a small relational database we already maintain, so please keep connectivity flexible. The finished story must present our KPIs through interactive charts, clean tables and an intuitive map view. Think drill-down, filter panels and responsive layouts that look just as good on a laptop as on the SAC Mobile App. Performance is critical; the dashboard should open quickly and refresh without noticeable lag, even when running live against HANA. I will provide access to the HANA views, API endpoints and a sample of the external database. You will model t...
I need an expert who can take my existing Google Merchant Center, Google Analytics (GA4), and Google Search Console accounts and connect them properly to my Shopify store. The goal is to have every piece of data flowing cleanly so I can see—at a glance—exactly how products perform, which campaigns drive revenue, and how shoppers move through the site. Here’s what I expect when the job is complete: • Google Merchant Center fully synced with Shopify, with all products approved and any feed or policy errors resolved. • GA4 configured to track sales, conversions, user behaviour, navigation paths, traffic sources, and campaign performance. Key events such as add-to-cart, checkout started, and purchase must fire reliably. • Google Search Console verified and lin...

The task centers on wiring up Dynamics 365 CRM to a set of REST-based webservices that are already published behind AWS API Gateway. Roughly 100 flows must be designed and deployed, each one synchronising data changes through an outbox pattern so every customer-, sales- and service-related event is delivered exactly once. Scope of work • Build and configure 100 integration flows that move data between Dynamics 365 Marketing and Customer Service modules and the existing API Gateway endpoints. • Implement the outbox pattern inside Dynamics 365 to ensure reliable, replay-able messaging. • Authenticate every call via AWS Directory Service (Active Directory) so the integrations inherit current IAM policies. • Surface integrated data back in Dynamics 365 dashboards to ...

I regularly import a CSV file into Excel. All of its dates arrive in the MM/DD/YYYY format, and I need them to stay that way once the data is in my workbook—no automatic regional flips, text-to-columns fixes, or manual corrections every time. I’m looking for a quick, repeatable solution inside Excel (VBA, Power Query, or any reliable built-in method you recommend) that: • Reads the incoming CSV • Persists the MM/DD/YYYY structure in every date column • Leaves the rest of the numeric data untouched Please deliver a working file or macro plus a brief, step-by-step note so I can apply it to new CSVs in the future.
I need a specialist who can wire several production-level databases together so that information flows in real time, is captured accurately, and remains easy to trace long after it lands in storage. The job starts with building the live integration layer: connections, transforms, and routing must update immediately as changes occur in the source databases (no batch or nightly jobs). Once the stream is flowing, I want a solid verification routine to run alongside it. Data consistency checks should flag mismatches, duplicates, or missing fields the moment they appear, then write clear exception logs I can review. This audit trail will be the backbone of weekly compliance reviews. All incoming files—whether produced by the integration or uploaded manually—should sit in an organi...

The feeds between my Revolut Business account, Shopify store and Xero ledger are either missing or out of date, so deposits, withdrawals and transfers are no longer matching the statements. I need the three platforms linked correctly, a clean reconciliation of the backlog, and a simple workflow that keeps everything in sync from today onward. Scope of work • Connect Revolut, Shopify and Xero so that data flows automatically without manual CSV uploads. • Bring all historical transactions into Xero, then reconcile every line against the bank statement until balances agree. • Configure rules or automation in Xero (or the relevant app connector) so future deposits, withdrawals and transfers post to the right accounts with minimal intervention. • Document the proces...

I have two separate workflow forms already running in Formstack, but maintaining them individually is creating confusion for my team and for the people who submit them. I need a freelancer who can merge these into a single, streamlined form while keeping every existing field, rule, and approval step intact. The combined form must continue to: • accept text inputs, file uploads, and multiple-choice selections exactly as they do now • email any uploaded files to the same recipients the current workflows use (rather than storing them elsewhere) Please map out all conditional logic, consolidate overlapping sections, and then build the new form directly in my Formstack account. Once you are done, I’ll test the end-to-end flow; if everything routes and emails correctly ...
I’m putting together a data-processing pipeline that blends the strengths of Java and Python. The goal is simple: pull data from several sources, cleanse and transform it, perform lightweight analysis, and push the results downstream in a form that is easy for other services to consume. Whether the flow ends up running in real time, on a schedule, or as classic batch jobs is still open for discussion, so versatility with both approaches will be appreciated. You will design and code the core pipeline components, set up automated tests, and leave behind clear documentation so the in-house team can extend the work without a hitch. Modern tooling is expected—think Maven or Gradle for Java, virtualenv or Poetry for Python, Git for version control, and whatever lightweight orchestra...
I need a detail-oriented specialist to take charge of a large batch of customer information currently sitting in Microsoft SQL Server database files. The work is twofold: first, bring new test records into the existing schema without breaking referential integrity; second, audit what is already there, flag inconsistencies, and correct them so the dataset is ready for stress-testing upcoming features. You will be working directly inside SQL Server, so fluency with T-SQL, bulk insert methods, and data validation queries is essential. Accuracy matters more than speed; I want every imported row, every updated field, and every deleted duplicate backed by a quick note or script so I can trace changes later. Deliverables (all discrete and specific): • Clean, de-duplicated customer ta...
I want to turn the raw data already sitting in our Microsoft Dynamics AX 2012 environment into a set of interactive financial dashboards. The core view I am after must let me track revenue, expenses, cash-flow movements and overall profit-and-loss at a glance, with the ability to drill down to the underlying AX transactions whenever needed. All data lives in AX today, so the job centres on connecting to those existing tables (or cubes if you prefer) and surfacing the numbers in an intuitive layout. Whether you choose SSRS, Power BI, or another front-end commonly paired with AX 2012 is up to you, as long as the result refreshes automatically and loads quickly for everyday use. Acceptance criteria • Dashboards render cleanly in a browser and on a 1080p monitor without additional...
Each month I prepare a performance snapshot for 13 dealerships plus an overall group roll-up. I now want a single Excel workbook that draws fresh data from four places—CRM exports, my boss’s Google Sheet, a marketplace XLS from our reps, and an invoice file that lists VDP views—and transforms it into a clear one-month and three-month view. The finished workbook should open on a summary sheet that shows every store on its own row, followed by a group total. For each row we need all the KPIs we already track online: Cars Online, Leads, Leads per Car, the marketplace benchmark for that ratio, VDP Views, VDP Views per Car, its benchmark, Dealership Visits, Budget and Cost per Visit. Leads per Car, Dealership Visits and Cost per Visit must stand out visually because my GMs ac...
I run a service-based company where too many day-to-day inventory tasks are still handled by hand. The resulting bottlenecks slow our operations and make it hard to scale, so I’m looking for a developer who can design and implement a technology solution that automates our entire inventory-management flow. What I need • A streamlined system—web, desktop or mobile—that records stock movements in real time, updates quantities automatically, and issues low-stock alerts. • Easy integration with our existing billing platform through REST or GraphQL APIs so we never have to re-enter data. • Role-based dashboards for staff and managers, giving each team member exactly the information they need. • Exportable reports (PDF/Excel) for weekly and monthly r...
I need an advanced data-feed solution that plugs straight into the Quotex platform and streams real-time market prices for binary instruments without delay or throttling. My priority is price accuracy and low-latency delivery; trade volumes or macro-economic releases are not required at this stage. Here is what I have in mind: • Direct, continuous price updates for the binary markets available on Quotex • Integration via the most efficient method you can offer (API, WebSocket, or a custom bridge) • A lightweight interface or script so I can quickly verify tick-by-tick values against the native Quotex chart • Clear, commented code and a short setup guide so I can redeploy the feed on another machine if needed Acceptance criteria • Latency consistently under ...
