I’m ready to commission a web-based retail analytics platform that connects directly to my data in Google Cloud SQL and presents it through an intuitive, modern dashboard. The application has to render a rich mix of chart types—bar, line, pie, heat-maps and anything else we decide is useful. Secure, scalable architecture is a non-negotiable. I expect the system to support at least 100 concurrent logins without performance drop-off, so please plan for horizontal scaling and efficient query tuning on GCP. Authentication must rely on OAuth (or an equivalent two-factor flow) and every user should land in the correct role the moment they sign in. An admin console will sit behind its own route. From there I want to: • create, edit and deactivate users • assign or change roles • fine-tune granular permissions for features and data access For analysts who aren’t feeding data through Cloud SQL, the UI needs a file-upload component that accepts CSV and Excel so they can run quick ad-hoc studies against the same visual engine. On the front end I’m looking for a fluid, responsive experience—think React with Material UI or an equally slick framework—so the charts resize gracefully across desktop and tablet. Back-end technology is flexible as long as it pairs cleanly with Cloud SQL and meets the performance targets. Deliverables I’ll sign off on: 1. Source code in a Git repository with clear setup instructions. 2. Deployed demo on a GCP project I provide. 3. Documentation covering architecture, environment variables and scalability guidance. 4. A thorough hand-over session walking through the codebase and admin tools. 5. Complete handover of code and ownership should happen at the end of the project Note: All project discussions need to be confidential and any portion of code cannot be shared with anyone If you have relevant examples, especially dashboards tied to cloud databases, include a link when you respond. I’m ready to start right away and will be actively engaged for feedback throughout the build. Note: Upon successful delivery of a high quality product, there is a great possibility of extension of this engagement
