About this gig

A connected, multi-user app native on iOS or Android, with a real backend behind it. One person designs the product, builds the app, and builds the API that powers it.


What's in scope: Native iOS (Swift / SwiftUI) or native Android (Kotlin) one platform per order Custom backend in Node.js / TypeScript, deployed (Railway, Fly.io, or your provider) PostgreSQL database, schema designed for your product Auth: email + password, Sign in with Apple, Sign in with Google REST API with the endpoints your app actually needs Push notifications Basic admin tools to manage users and content


What's NOT in scope (be honest with yourself): Real-time features at scale (live chat, multiplayer, video streaming) Marketplaces with multi-party payments and complex payouts Recommendation engines, ML pipelines, or AI model training High-traffic infrastructure (we're shipping an MVP, not scaling Amazon) Cross-platform (iOS + Android in the same order order Gig 2 twice or contact me) Web companion app see Gig 4 for that

Think: habit tracker that syncs across devices, niche social app, journaling app with cloud backup, focused community app, B2B internal tool with a mobile front-end. Not: TikTok, Uber...

I'm a Full-stack Product Designer and Product Engineer. 15 years shaping digital products, 7 years shipping native iOS in Swift. I also build native Android, full-stack web, and backend. The rare part: one person designs AND develops end-to-end. Your product moves from UX to a shipped, production-grade build with no handoff between designer, mobile devs, and web team — and no agency overhead. Best for founders launching their first product, or teams who want one senior operator instead of an agency. Tell me what you're building.
