    I need a clean, interactive dashboard that lets our management team see at a glance how well we are moving product from warehouse to customer. The focus is delivery progress, so the visuals must surface three core metrics: on-time deliveries, route efficiency, and customer satisfaction scores. Data sources are already available in our internal SQL database and a daily CSV export from our last-mile partner. I can supply sample tables and field definitions; you will handle the ETL so the numbers refresh automatically each morning. A browser-based tool such as Power BI Service, Tableau Online, or a lightweight React-D3 build is fine—whichever you are fastest with.

    I will turn your raw business data into a clean, reliable model and then build a modern Power BI—or, if you prefer, Excel—dashboard around it. Using SQL and Power Query I’ll handle the full preparation pipeline so every refresh runs automatically. The finished dashboard will surface your key sales, order, and performance indicators through intuitive charts, drill-through views, and slicers that non-technical users can explore with confidence. Colour palette, fonts, and layout will match your brand, and advanced filters will let you zero in on any segment or period in seconds.

    I am building a green-field fraud-detection platform and need an experienced back-end engineer to own the server-side work for the next three months. The stack is .NET (C#), PostgreSQL, and Redis; a separate team will handle the React front end, so your focus stays firmly on the APIs, data layer, and real-time processing pipeline. What the engagement looks like You will translate our detection logic into clean, well-tested C# services, design the relational schema in PostgreSQL, and use Redis for low-latency caching and message queues. Because the app is completely standalone, there are no third-party or legacy integrations to worry about—every decision you make will directly shape the core product.

    I need a production-ready backend that powers a multi-tenant School Management SaaS. The stack is fixed—ASP.NET Core 8 Web API with EF Core and SQL Server—so you should be completely comfortable designing clean, modular code in that environment. Core scope • Build the entire API layer only; no front-end work. • Architect true multi-tenancy from day one, separating data per school while keeping shared services efficient. • Implement rock-solid authentication and authorization, plus fine-grained role-based access control. Day-to-day users include Students, Teachers, Parents, School Admins, Platform Admins and other school-specific roles, so permissions must be both flexible and secure. • Model every major domain: school setup/configuration, student/pa...

    I am a recent graduate and want a structured skill-development course that takes me from absolute beginner to confident practitioner in data analysis. The program should combine theory with plenty of hands-on practice so I can start applying what I learn right away. What I expect • A clear learning path that begins with fundamental concepts (data types, basic statistics, exploratory analysis) and steadily introduces more advanced topics. • Practical exercises and mini-projects using widely adopted tools such as Excel, SQL and Python (Pandas, NumPy, Matplotlib or similar), so I can build a small portfolio along the way. • Short quizzes or checkpoints after each module to confirm I have grasped the material. • Real-world datasets for practice plus guidance on where...

    A new Siemens-based material-handling line is ready for commissioning and I need a clean, well-structured PLC project that focuses on data acquisition and logging. The controllers are Siemens S7 (TIA Portal) and the HMI layer will sit on WinCC (Unified or Classic—whichever you are most comfortable with). Core objective Capture and store real-time Operational status from drives, conveyors, and sensors so that maintenance and performance dashboards can draw from a reliable historical database. Inventory levels and movement tracking may be added later, so please structure tags and DBs with scalability in mind. Scope of work •⁠ ⁠Write the PLC logic that collects the required status bits, words, and alarms. •⁠ ⁠Build WinCC screens for live visualization, manual overrid...
