No local usernames or social-logins—just Azure AD with proper role mapping. • After authentication, customers need the usual CPQ flow (configure → price → quote → checkout) and, on completion, the system must call the license server’s API to create or update the customer’s subscription license automatically. • Every product in the catalogue is subscription-based, so the cart, checkout and subsequent renewals have to respect recurring-billing rules.

    [Chennai-based freelancer is preferred as a visit to the customer's site may be necessary] My custom HTML dashboard is almost production-ready, but two areas still hold it back: WebSocket data transfer errors and overall front-end performance. The interface is built with vanilla HTML/CSS and JavaScript, streaming live data from a Cognex industrial machine vision camera over WebSocket. While the socket connects successfully, packets occasionally arrive corrupted or out of order, which breaks the real-time charts. I need you to trace the exact cause of these data transfer errors, patch or rewrite the send/receive logic as needed, and add graceful handling for edge cases such as dropped frames or partial payloads.

The plan is to host the Spring Boot API and the React build on Azure App Service and wire everything up to an Azure SQL Database. What I need you to do • Create or refine the Azure resources (App Service + Azure SQL Database). • Set up the build and deployment workflow so every push to the repository triggers a fresh deployment of both the React static files and the Spring Boot jar. Azure DevOps or GitHub Actions is fine as long as it is reliable. • Configure environment variables, connection strings, and SSL settings so the API talks securely to the database and the front-end talks to the API. • Validate that the site loads, ...

The core flow I have in mind: • The system schedules questions using a proven spaced-repetition algorithm (SM-2 or equivalent) and presents them through a friendly chat interface. • I type my full answer; the chatbot uses NLP to highlight strengths, missing points, tone, or structure, then suggests concrete ways to refine the response. • All attempts, feedback, and review intervals are stored so the dashboard can show accuracy trends, time spent, and next-due items.
