Mobile App Development

React Native · Expo · iOS & Android

I build apps that run on iOS and Android from a single codebase. Using React Native and Expo, I handle the full journey from prototype to App Store release — design, engineering, AI integration, and store submission included. No separate team, no coordination overhead. Scope is locked up front, price stays fixed, and you see something working every Friday.

How it works

In the discovery phase we agree on the problem, the audience, and the constraints — before any code, with a written brief. During the build phase, design and engineering run in parallel; you get a live demo every week with shared Linear and Figma. At handoff, I transfer the repo, infrastructure, and docs into your name, and a 30-day care period begins.

Why me?

I shipped AI-powered mobile apps like Aril and ÜRE from scratch, solo — design decisions, AI integration, and store release all included. No separate PM or UX team — you work directly with me, the person who built it.

FAQ

How long does a project take?
A prototype takes 1–2 weeks, an MVP 4–6 weeks, a full app 8 weeks or more. Scope is agreed up front; timeline follows from that.
How does the contract work?
Every project starts with a written scope and price agreement before any work begins. If the project is cancelled mid-way, only completed work is invoiced.
Do you handle store submission?
Yes. App Store and Google Play submission — screenshots, metadata, and review coordination — is included in the MVP and Full tiers.
Who owns the source code?
You do. At handoff, all source code, repo access, and infrastructure credentials are transferred to your accounts. No licence lock-in.
Do you work with international clients?
Yes. All communication runs in English, invoices can be issued in USD. Time-zone differences are managed through weekly demos and async updates.
