Are you a backend engineer who enjoys debugging, improving existing systems, and completing real product features in a fast-moving startup environment? We are building a platform for the foodservice industry focused on bid management, rebates, contracts, invoices, and document automation. We are looking for a backend developer to help us fix, complete, and stabilize several important modules in our application. This will begin as a paid trial project. If the work is completed successfully, there is an opportunity for ongoing development work as we continue to grow.

If possible, you must complete this within this week. Please do not send the proposal if you cannot work on the weekend or have other ongoing projects. We do not prioritize low prices; instead, we are willing to pay for the best quality.

Seeking proven and Node.js development experience to build a production-ready REST API backend that will authenticate to Microsoft Power BI via Azure AD service principal, generate time-limited embed tokens for secure dashboard rendering, and retrieve real-time operational metrics from Power BI datasets using DAX queries. The system will integrate with the Anthropic Claude API using healthcare-specific system prompts, persist all analyses and audit logs in PostgreSQL with immutable compliance tracking, and deploy to Azure App Service with robust error handling, logging, and monitoring. The engagement includes full integration testing and a comprehensive security review prior to launch. ⚠️ All data in the Lovable frontend is currently generated by React components using hardcoded mock objects.

The primary objective for the data engineer is to deliver a secure, multi-tenant backend, replace all mocked page data with live API responses, embed Power BI dashboards with row-level security, and stand up a Claude-driven analytical agent that operates over a governed semantic model. SUCCESS CRITERIA 1. All 3 endpoints deployed and tested 2. Frontend Dashboard.tsx renders real Power BI embed 3. Frontend AIInsights.tsx displays Claude analysis 4. ActionPlanContext replaced with server-backed CRUD 5. PostgreSQL audit log captures all API calls 6. Security review passed 7. Load test: 50 concurrent users, less than 300ms p95 8. Power BI RLS verified between test orgs 9. Documentation + runbooks delivered 10. Zero unhandled errors in production 11. Launch in mid-June 2026
