I help founders build, improve, and test React Native mobile apps. I can implement a focused feature, integrate an API or subscription flow, investigate a bug, or review a release for usability and functional issues. Deliverables are agreed upfront and may include code changes, QA findings, setup notes, and a short handoff. I founded and built FlowMoney, a personal finance app for US gig workers that is live on Google Play. My hands-on stack includes React Native, TypeScript, RevenueCat, and Vercel. Share a repository or test build, the target platforms, and a concise scope to get started.
