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.

Job Description Project Overview We have a fully code-complete Micro-SaaS platform called BounceBack SMS. The app is an automated missed-call text-back and lead recovery system built using Next.js 15, Tailwind CSS, Twilio API, and Supabase. The repository is isolated, structured, and securely hosted in a private GitHub repository. We are looking for an experienced Full-Stack/DevOps Engineer to handle the production deployment, configure live API pipelines, manage database environment mapping, and ensure the entire setup runs on a frictionless, automated continuous integration/continuous deployment (CI/CD) framework. Scope of Work (Key Deliverables) 1. Infrastructure Mapping & Production Deployment Deploy the Next.js 15 frontend/backend application from our private GitHub repository to production hosting (Vercel/Render). Map and connect production environment variables, database schemas, and connection strings to our live database instance (Supabase/PostgreSQL). Configure a permanent automated CI/CD pipeline (e.g., GitHub Actions or Vercel integration) ensuring any future push to the main branch automatically rebuilds and deploys the app flawlessly. 2. Twilio API & A2P 10DLC Compliance Configuration Connect and secure our live Twilio API gateways within the backend architecture. Audit and verify that our messaging endpoints cleanly support incoming webhooks for missed-call detection. Crucial Milestone: Assist and audit our US A2P 10DLC Campaign Registration via Twilio to ensure 100% carrier delivery compliance (Privacy Policy and Terms pages are already live and coded in the repo). 3. Live Stripe Billing Integration Transition our checkout environment variables from Stripe Sandbox/Test Mode into Live Production Mode. Wire up our exact pricing architecture: $0 Setup Fee, 100 Free Leads Usage Trial, transitioning into a flat $19.99/Month Recurring Subscription. Ensure Stripe webhooks are completely listening to successfully provision, pause, or update customer account access tiers inside our database based on subscription state. 4. Handover & Bulletproof Documentation Provide a brief, plaintext .txt or .md technical handover file outlining the deployed environment structure, a list of active API webhooks, and step-by-step instructions for simple environment variable updates. Required Tech Stack Expertise Frameworks: Next.js 15 (App Router), React, Tailwind CSS Database: Supabase / PostgreSQL (Schema sync, migrations, security policies) APIs: Twilio SMS Gateway (Webhook architecture, A2P 10DLC registration compliance) Payment Rail: Stripe Billing API (Usage-based trials, recurring webhooks) DevOps/Version Control: Git, Private GitHub Repositories, Vercel/Render, CI/CD automation Preferred Qualifications Proven track record deploying independent Micro-SaaS or automation applications. Deep familiarity with strict US telecom carrier A2P SMS delivery guidelines to prevent messaging blocking or spam flags. Obsession with clean environment variable separation—absolutely no hardcoded credentials. Excellent technical communication skills and availability to run live end-to-end integration testing before final milestone sign-off. 🎯 Candidate Screening Questions (Include on Upwork) 1. Briefly describe your experience configuring Twilio webhooks and handling the US A2P 10DLC registration process to ensure high carrier delivery rates. 2. How would you configure Stripe to trigger a recurring $19.99/mo flat-rate subscription specifically after a user consumes exactly 100 free database actions/leads? 3. Confirm that you are comfortable working out of a private GitHub repository and setting up an automated CI/CD pipeline so I never have to manually pay for developer redeployments.

# Overview We're a healthcare analytics company with an internal web portal (built in **Next.js 16 / React 19 / TypeScript / Tailwind CSS v4**) that embeds Power BI reports for our partners. The app works, but it was built quickly and needs to be brought up to a **production-quality standard**. It's a small, focused codebase (~2,400 lines), so this is a high-impact, well-scoped engagement — not a sprawling legacy rescue. We're looking for a senior frontend engineer to either **refactor the existingcode or rebuild it from a clean foundation** (your call — we want your recommendation), and to leave us with a maintainable, tested, polished application. # What you'll be working on A single Next.js App Router application that: - Renders a landing/navigation experience and a set of dashboard pages. - Embeds Power BI reports via `powerbi-client-react` ("App Owns Data"). - Reads a small amount of data from Postgres for user settings. **Authentication is fully handled upstream (SSO) and is OUT OF SCOPE.** You will never need credentials, secrets, or access to our production environment. (See "How we work" below.) # Scope of work 1. **Code quality & structure** — Establish a clean, consistent architecture: sensible component structure, strict TypeScript, and tooling (ESLint + Prettier). The repo currently has no linting or formatting setup. 2. **Testing & CI** — Add a testing setup (unit + a few integration/e2e tests for critical paths) and GitHub Actions CI gates (lint, typecheck, test on PR). There are currently **no tests** — establishing this foundation is a core deliverable. 3. **UI / UX polish** — Implement to our provided design direction: responsive layout, proper loading/error/empty states, and a polished feel around the (heavy) Power BI embeds. **We will provide the design/branding** — you implement it well, you don't need to invent the visual identity. 4. **Recommendation up front** — In an early milestone, give us a short written assessment: refactor vs. rebuild, and your proposed approach. **Out of scope:** authentication/SSO, SEO (the app is private and login-gated), backend/Power BI infrastructure, and anything touching production data. # Required skills - Deep, demonstrable experience with **Next.js (App Router)**, **React 19**, and **TypeScript** (strict mode). - **Tailwind CSS** proficiency and a strong eye for implementing designs faithfully. - Experience setting up **testing (e.g. Vitest/Jest + Playwright)** and **CI pipelines (GitHub Actions)** for frontend apps. - A track record of taking quick-build apps to **maintainable, production-grade** quality. ### Nice to have - Prior **Power BI embedding** experience (`powerbi-client-react`, "App Owns Data") - Accessibility (WCAG AA) and frontend performance optimization experience. # How we work (please read) - We operate in a regulated healthcare environment. You will work against a **sanitized copy of the repository** — no real report IDs, secrets, customer data, or production access. All data is mock/synthetic. - **Hourly engagement** via Upwork's tracker, with a cap. We estimate **~40–100 hours**; we'll set a weekly cap and review progress in milestones. - We value clear communication, small reviewable PRs, and your honest technical judgment over just "doing what's asked."
