The spec is done. The data model, every API route, all 9 screens, and a 46-step build sequence are written out in full. You will never wonder what to build next. I need a React Native developer to turn that document into a working iOS and Android MVP in two weeks. The stack is already decided: React Native + Expo, Fastify backend, Postgres, Cloudflare R2 for photo storage, RevenueCat for subscriptions. This is a Claude Code project. I expect you to use it. If you know how to work with AI-assisted development at speed — feed a spec, review output, iterate fast — you will move through this quickly. If you prefer to write every line manually, this is not the right fit. At the end of two weeks I need: - Working camera flow on both iOS and Android simulators - Photos uploading and retrieving from cloud storage - Projects, gallery, timeline, and tag screens functional - Short README for onboarding One question when you apply: show me something you've shipped in React Native and tell me which AI dev tools you use daily.

Hello, I will deliver your construction photo app MVP within the two-week window — camera flow, cloud upload/retrieval via R2, project/gallery/timeline/tag screens, and the onboarding README. All built with Expo, Fastify, Postgres, and RevenueCat as specified. With a 46-step build sequence already mapped, I will use Claude Code to move through each step rapidly — feeding spec sections, reviewing output, and iterating. One thing I will prioritize early: configuring R2 multipart uploads with client-side image compression before hitting the network, so large construction photos do not bottleneck the upload flow on job sites with poor connectivity. I am happy to share relevant React Native work and my AI tooling workflow in chat. Looking forward to discussing further. Best regards, Kamran

Hi, This is very doable, but the success of a two-week build depends on keeping the critical path stable, not just moving fast. The real goal here is getting a reliable capture-to-cloud flow working across both platforms, because everything else in your app depends on that behaving predictably. The main failure point in builds like this is the photo pipeline: camera permissions, file handling, upload retries, and storage sync. If that layer is even slightly unstable, the rest of the app may look complete but won’t hold up in real use. I’d focus first on locking that flow end-to-end, then layer in projects, gallery, and timeline features on top of a stable base. Using AI-assisted dev is fine, but I treat it as acceleration, not a substitute for control over the architecture. I’d start by validating the camera/upload/storage loop on both platforms before expanding screens.

Hi, This is exactly my workflow—spec-driven + AI-assisted rapid delivery. With your detailed 46-step plan, I can move fast and hit the 2-week MVP target. Stack: React Native (Expo) + Fastify + Postgres + Cloudflare R2 + RevenueCat — all familiar. How I’ll execute: • Use Claude Code / AI tools to accelerate scaffolding + boilerplate • Manually refine critical flows (camera, uploads, state, performance) • Daily iteration: build → test → optimize Core features delivery: ✔ Camera flow (iOS + Android) ✔ Image upload/retrieval (R2, signed URLs, caching) ✔ Projects, gallery, timeline, tagging ✔ Clean state management + API integration ✔ Subscription setup (RevenueCat-ready structure) AI tools I use daily: Claude, ChatGPT, GitHub Copilot — for rapid generation + validation (not blind copy). Recent work: Built React Native apps with media uploads, offline handling, and API-driven dashboards (can share demo/screens). Timeline: Day 1–3: Core setup + auth + camera Day 4–8: Uploads + gallery + APIs Day 9–12: Screens + tagging + polish Day 13–14: Testing + README + delivery Deliverables: • Working MVP on simulators • Clean repo + README Ready to start immediately and move fast.

Hello, your note about having the full spec, data model, and 46‑step sequence already defined caught my attention , that level of structure makes fast iteration with AI tooling genuinely effective. I've delivered several React Native + Expo builds that required tight timelines, including a field‑photo capture app that shipped with a Fastify API and R2 storage pipeline, and a subscription layer where I integrated RevenueCat for gated features. The real challenge here is maintaining consistency between the spec, the Fastify routes, and the AI‑generated code , especially around camera flow, binary uploads to R2, and state syncing for gallery and timeline. If not supervised well, AI tools drift; I prevent that by validating each module against the schema before integration. I’ll scaffold the Expo app, wire the Fastify endpoints, implement the camera workflow, handle R2 upload/retrieval, and finalize the Projects, Gallery, Timeline, and Tag screens. I keep AI‑generated code isolated per module to ensure traceability and quick rollback. Before I begin, let me know the format of the spec (Markdown, PDF, Notion) and whether the Fastify server will run locally or via a cloud dev environment. This can be built cleanly within your two‑week window. Thanks, John allen.

Hi, This is exactly the kind of fast, spec-driven build I work best with. I’ve shipped React Native apps using Expo, including camera flows, cloud uploads, and API-driven features. I’m comfortable working with Fastify, Postgres, and cloud storage (R2/S3-style), and integrating subscriptions via RevenueCat. I actively use AI-assisted dev tools (Claude Code, ChatGPT, Copilot) to move fast — feeding structured specs, validating outputs, and iterating quickly while keeping code clean and production-ready. I focus on delivering fully working features across iOS & Android, not just partial builds. Happy to share examples and walk through how I’d execute your 46-step plan efficiently.
