This project involves the creation of a browser-based web application for my established business. The app will periodically ingest and parse Excel files into a structured database, and it will connect to a PLC via OPC UA to validate QR codes and exchange PASS/FAIL test results. Key Requirements: - Frontend: Must be built with React + WebSockets to display real-time, station-specific data on two monitor instances (Station 1 & Station 2). - Backend: Developed using Flask + Python OPC UA client to manage data synchronization, database updates, and OPC UA communication. - On-premise Solution: The application should run on-premise and include a stubbed OPC UA server for testing. - Deliverables: The project should deliver fully documented code, automated tests, and deployment scripts. Freelancers must include a detailed project proposal in their application, showcasing their understanding of the project requirements and demonstrating their relevant experience and skills. A proven track record in developing similar web applications and working with OPC UA is a plus. The successful completion of this project is required within a month. --- Above is generated by AI of freelancer website. For more tech details , please find my PRD attached. Please check that and quote. To avoid spam, I have inserted a generic question, and request bidders to start their bid by answer to that question which would then help me filter for them. I had similar but smaller requirement which I posted earlier earlier, but further conversation with client led to major changes, including major requirements of coordinating with PLCs as well. This PRD covers the IT part of total system. For OT part, I may post separately.
