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. There is no backend API, no database persistence, and no real data sources. This is the scope of work for your backend engineer. 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

We are building a HIPAA-compliant SaaS platform for medication stewardship in skilled nursing facilities (SNFs). The platform allows clinical pharmacy consultants and providers to upload scanned medical documents, run AI-powered medication and disease state reviews, and generate clinical findings — all without storing any patient data. This is a focused, well-defined MVP. No scope creep. We need a developer who moves fast, communicates clearly, and has real experience with HIPAA-eligible AWS architecture. Core concept — stateless processing: This platform is intentionally stateless. Documents are uploaded, processed through OCR, analyzed by AI, and the findings are displayed to the user. Nothing is written to a database. No patient data or documents are retained after the session ends. The platform processes PHI transiently and discards it — significantly simplifying the HIPAA footprint while maintaining compliance. What you will build: 1. AWS infrastructure (HIPAA-eligible, stateless) — S3 used only as a temporary processing buffer (files deleted immediately after OCR completes) — AWS Textract for OCR processing of scanned PDFs and images — AWS Bedrock (Claude Sonnet) for AI-powered clinical analysis — AWS Cognito for user authentication only (no clinical data stored) — AWS Amplify or CloudFront for React frontend hosting — KMS encryption for data in transit — All services configured under AWS BAA coverage — No RDS or persistent database required for clinical data 2. React frontend — Clean single-page application — Document upload UI (drag/drop, supports PDF and image files) — OCR text display with basic edit capability before analysis — Free-text question input (user asks Claude questions about the document) — Claude response display panel — Copy to clipboard button on all output — User login and profile page (name, email, facility) — Membership and billing settings page — Stripe monthly subscription integration 3. HIPAA compliance — Stateless architecture — no PHI persisted after session — HTTPS enforced on all endpoints — AWS BAA signed and covering all services — User BAA acknowledgment on signup — Audit logging for access events — Privacy policy and terms of service integration What we are NOT building in this phase: — Mobile app — EHR or PointClickCare integration — Stored intervention history or dashboard — Cost savings calculator — Admin panel — Anything beyond the three core features above: upload, analyze, copy output Ideal candidate: — 3+ years React and AWS experience — Prior HIPAA-eligible AWS builds — please describe your specific experience in your proposal — Hands-on experience with AWS Textract or comparable OCR pipelines — Familiarity with AWS Bedrock or direct LLM API integrations — Experience with stateless or ephemeral data processing architectures — Stripe subscription integration experience — Strong communicator — weekly video check-ins required — Available to start within 2-4 weeks Engagement details: — Estimated scope: 40–60 hours — Timeline: 8–10 weeks — Budget: $2,500–$4,500 USD fixed price preferred — Payment milestones: 25% upfront, 25% at working OCR pipeline, 25% at working Claude integration, 25% at launch — Communication: Weekly video check-in + async messaging How to apply: In your proposal please answer these four questions specifically: 1. Describe a HIPAA-eligible AWS application you have built — what services did you use and how did you handle PHI? 2. Have you implemented stateless or ephemeral document processing before? How did you approach it? 3. What is your experience with AWS Textract or other OCR pipelines? 4. How would you integrate AWS Bedrock or a Claude API call into a React frontend securely? Proposals that do not answer these four questions will not be considered. About us: We are an early-stage clinical SaaS platform founded by a Clinical Pharmacy Specialist. We are building a tool that genuinely improves patient care and safety in long-term care settings. We want a developer who takes pride in clean, secure, well-documented code and wants to be part of building something meaningful in healthcare. If that is you, we would love to hear from you.

OVERVIEW I'm building Inkora, a subscription web app: an AI creative-writing companion for fiction (romance, fan fiction, poetry, general fiction). The React front-end is COMPLETE and will be provided, with clearly marked integration points. I need the backend built, connected, and the full app deployed. This is an 18+ platform with content safeguards. STACK ALREADY IN PLACE - React front-end (provided; single-file app ready to be scaffolded into a project) - GitHub (repo will live on my account) - Vercel (hosting, my account) - Stripe account created - Anthropic (Claude) API key — must live server-side only, never in client code - Domain: inkora.com SCOPE OF WORK 1. Secure AI endpoint — a serverless endpoint (e.g. POST /api/write) that attaches the provided system prompt, calls the Claude API with the server-side key, and returns the text to the front-end. Suggested writing model: claude-sonnet-4-6. 2. Content moderation — screen user input BEFORE the model call and model output AFTER it. Block sexually explicit content and gratuitous graphic gore. Use a inexpensive-model screen (e.g. Haiku) or a third-party moderation API. Log violations; support a warn-then-suspend flow. 3. Auth — your recommendation (Supabase or Firebase preferred). Email + password baseline; Google sign-in if low effort. 4. Database — persist each user's stories (title, genre, full message history, timestamps), characters, and notes. The front-end already models these data shapes. The story's full saved history must be sent with each AI request (this powers in-story continuity). 5. Subscriptions (Stripe) — $10/month, ~$27/quarter, ~$96/year. Free tier: 10 messages per day (make this a config value), resetting every 24h. Gate writing access by subscription status / remaining free allowance. Handle the subscription lifecycle via webhooks. 6. Age-gate persistence — the front-end collects date of birth + an 18+ affirmation; store the affirmation timestamp with the account. Structure it so a third-party age-verification provider can be swapped in later without reworking the flow. I'm open to building on a proven starter/template (e.g. the Vercel AI chatbot template) if it speeds things up — adapting solid existing code is welcome. DELIVERABLES - Deployed, working app (provided front-end + your backend) on my Vercel, repo on my GitHub - All secrets configured as environment variables (never in client code) - Short handoff notes: key rotation, where moderation logs live, how to change config values WHAT I PROVIDE - Complete front-end code, a written backend brief, and the system prompt (shared privately with the selected freelancer) - All accounts (GitHub, Vercel, Stripe, Anthropic) already created and ready TO APPLY, PLEASE ANSWER THESE IN YOUR PROPOSAL: 1. Have you wired Stripe subscriptions with webhooks before? Link or example. 2. How will you keep the API key off the client? 3. How would you implement input + output moderation cost-effectively? 4. Have you deployed serverless APIs on Vercel? 5. Your fixed quote and timeline for this scope. Proposals that don't answer these questions will not be considered.
