Our in-house created document control software has been running smoothly on a C#/.NET stack, MS SQL Server, and AWS for several years, but the developer who built and nurtured it is leaving. I need someone who can step in right away, understand the codebase, and keep the software/application stable and performant. The immediate focus is routine maintenance—diagnosing and fixing any bugs that surface and squeezing better performance out of the code, database, and AWS resources. I don’t have a current list of issues, yet I suspect the usual mix of edge-case errors and slow queries will emerge once you start profiling the system. You’ll get full access to the Git repository, SQL scripts, and our AWS environment (EC2, RDS, S3). A thorough walkthrough with the ...

...Mapping must be preserved so future updates keep everything aligned. • Order side When a customer places an order, the bridge catches it instantly, calls the supplier API to purchase the corresponding digital key, retrieves the key and posts it straight back through the store API so the customer receives it without delay. Technical notes – Both APIs are REST. – A small, fast database (SQL or NoSQL is fine) should sit in the middle for caching, mapping and deduplication. – On any failed call the bridge should automatically retry with exponential back-off; I’ll review other alerting/logging options later, but solid retry logic is essential from day one. – Idempotency is critical so duplicate orders never slip through. – Clean...

I need every figure lifted out accurately and keyed into the destination sheets I will provide so I can run consistent reports. You will receive read-only access to the database interface (along ...populate. Accuracy is the top priority—decimal placement, units and column order must match the template exactly. I will run spot checks, so an error rate above 0.2 % is unacceptable. Once complete, submit the filled spreadsheet plus a brief log of any ambiguous values you encountered and how you resolved them. If you have previous experience extracting data from custom databases rather than standard SQL or NoSQL engines, note that in your proposal; it will help me gauge fit and turnaround...

...on-demand and scheduled reports—profit & loss, cash-flow snapshots, trend charts, and any other analytics you recommend that help me spot patterns fast. • Export reports to PDF and Excel. I’m happy to discuss the stack, though a solution that feels native to Windows—think C#/.NET, WPF, WinUI, or similar—will be easiest for me to maintain long-term. A lightweight local database such as SQLite or SQL Server Express is fine, as long as backup and restore are simple. Deliverables 1. Installer or ready-to-run executable for Windows 10/11 2. Source code with brief build instructions 3. Short user guide that shows how to add data and run the analytics Acceptance criteria • Application installs without additional paid dependencies &bul...

In addition to the features outlined below, patients will be encouraged to stay engaged through an integrated blog section that delivers health tips and practice news. Stack and architecture • Back-end logic is planned in PHP for traditional server tasks and Node.js for any real-time components that benefit from non-blocking I/O. • A secure SQL database needs to be designed, populated, and tuned to store patient records, appointment data, doctor profiles, service catalogs, and log data.

...under load. Pages that once rendered in under a second now spike past five, occasional time-outs appear in the logs, and CPU usage sits uncomfortably high. I’m looking for help focused strictly on bug fixes and ongoing maintenance, with the immediate priority being performance bottlenecks on the server side. You’ll start by profiling the application (IIS, ASP.NET MVC / Web API, Entity Framework, SQL Server) to pinpoint slow spots—inefficient queries, memory leaks, or blocking calls. From there, I need clean, well-commented patches that restore sub-second response times under typical traffic and remain stable in our staging environment for at least 48 hours before deployment. Deliverables • Diagnostic report outlining root causes and performance metrics ...

I need to organise all of my customer information in a structured SQL database and give my team a simple way to add or update those records directly from their phones. The core of the job is two-fold: first, design and deploy a clean relational schema that captures names, contacts, addresses, notes and whatever other standard customer fields you would normally expect; second, build a mobile interface that lets users create, read, update and delete those records through straightforward forms. The mobile side can be cross-platform in Flutter or React Native, or native Android if that is faster for you—what matters most is that it connects securely to the database, validates input, and presents a searchable list of existing customers. No CSV imports or external APIs this time; e...

Build a single Power BI dashboard that pulls data live from my Excel workbooks and our SQL database, then turns that information into clear insights about customer demographics and customer satisfaction. The data model should merge both sources seamlessly, handle refresh schedules, and expose relationships that let me slice results by date, region, product line, and any other key fields you uncover. Inside the report, I want bar charts for quick comparisons, pie charts for proportional breakdowns, and line graphs that reveal trends over time—each fully interactive with tooltips, drill-through, and cross-filtering. Supply the finished .pbix file, document any custom DAX logic, and publish a ready-to-share version to Power BI Service (or show me how in a brief hand-off cal...

I need to turn two raw datasets—sales and customer records—into a clean, insight-packed dashboard. Start by profiling the data in Excel or SQL, removing duplicates, filling or flagging missing values, and standardising every date, currency and categorical field so the tables can join cleanly. With trustworthy data in place, build an end-to-end Power BI model: set relationships, create calculated columns and DAX measures, and surface the KPIs that drive our decisions (revenue trends, customer lifetime value, churn, product mix, regional performance). The visuals should be interactive, with slicers that let managers move from an executive overview down to line-item detail. Quick exploratory charts in Excel are welcome, but the final, shareable report must live in Power BI...
