# 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."

You'll be managing our .NET and Angular developers directly, so you need to be highly comfortable keeping complex software builds on track and speaking their language. Realistically, we need someone with at least seven years of experience under their belt, specifically leading large-scale enterprise ERPs built on Microsoft and modern web stacks.
