I own a car wash in Kirkland, WA, and I’m looking for a front and backend web developer to build a custom online membership checkout page for our existing website. The checkout page will allow customers to purchase monthly recurring car wash memberships online. It needs to connect with Sonny’s CarWash Controls using their ECommerce API and BackOffice Data API. The project includes membership plan selection, customer information collection, recurring membership checkout, payment integration, Apple Pay and Google Pay integration, a confirmation/receipt page, and a secure backend API connection to Sonny’s. This is not just a basic design project. I need someone who has experience with custom API integrations, ecommerce checkout flows, recurring billing, and secure payment handling. I already have the Sonny’s API documentation available. Local to the Seattle/Bellevue/Kirkland area is preferred, but I’m open to remote if you have the right experience. Please include examples of similar API, payment, or ecommerce checkout projects you’ve completed.

# 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."

What this is: I'm the founder of a working AI SaaS platform (FastAPI/uvicorn backend, React/Vite frontend, deployed on AWS). The product pipeline is built and live! I need an experienced engineer to build the authentication, payments, and usage-entitlement layer that gates the product behind login and paid usage. You'll work against a runnable stub repository (real routes + data shapes, proprietary internals removed) - so you can build and test the full layer without ever touching the core IP, and afterwards - I will merge your work into the production app! Scope: • Auth (Clerk): signup/login, session lifecycle, backend session/JWT verification, inject a validated `user_id` into protected endpoints. • Payments (Stripe): Checkout for purchasing usage credits, plus a webhook that credits the user's ledger on successful payment. The webhook MUST be signature-verified, idempotent (Stripe retries-credit exactly once), and reconcilable (handle webhook-failed-but-payment-succeeded). • Entitlement ledger (the core): a credit balance per user with atomic check-and-decrement (two concurrent requests must never double-spend) on PostgreSQL. A `check_entitlement(user_id, ...)`gate that expensive endpoints call before doing paid work. • Server-side route gating: enforce entitlement on every paid endpoint (not just hidden in the UI); clean 401/402/403 responses. • Frontend integration (React): login/signup UI, buy-credits/checkout flow, balance display,graceful "out of credits" states, wired to the above. • Tests for the money-critical paths (webhook idempotency, atomic decrement, gating-bypass attempts). Stack you'll work with: Python 3.11, FastAPI, Pydantic, uvicorn (Linux). React + Vite, Tailwind. PostgreSQL. Clerk. Stripe. Who I'm looking for: Someone who has shipped this exact kind of system to production before. In your proposal, briefly tell me: 1. How you ensure Stripe webhook idempotency and handle reconciliation when a webhook fails but payment succeeded. 2. How you'd implement the atomic credit check-and-decrement so concurrent requests couldn't double-spend. 3. A relevant production system you've built (Stripe + auth + usage metering ideally). *I'd much rather a short, specific proposal - than a long generic one!* Working with me: I'm an engaged founder who genuinely enjoys building, and I want this to be a good experience for both of us! I'm responsive, communicate clearly, and I respect your expertise - because you're the specialist here,and I'm hiring you because you know this much better than I do! I'm not a micromanager and I'm not nitpicky - I just want the end results to be solid! I review in milestones, asking questions because I like understanding the work (not because I'm second-guessing you), and I make decisions quickly so you're never stuck waiting on me! The scope is already well-defined (detailed spec + a runnable stub repo on engagement), so you're not pricing around a vague, shifting target - it's a clean, bounded build. I care about getting the money-handling pieces right, and I'm betting you do too - if that resonates, I think we'll work well together! IP / engagement: A mutual NDA + IP-assignment (work-for-hire) before repo access. You build against stubs; you won't receive the proprietary pipeline. Work is milestone-based, fixed-bid preferred. To apply: Answer the three questions above + share 1-2 relevant examples, and ballpark your timeline and milestone structure (suggested: auth → payments+webhook → ledger+gating → frontend → tests/docs)!
