Paul G.

Mobile App Developer

I build production-grade iOS and Android apps for clients who need polish, reliability, and a developer who ships. 5+ years, 14 deployed apps, full-stack mobile, native + cross-platform. My team and I design, build, and launch mobile apps across: - Native iOS (Swift, SwiftUI) - Native Android (Kotlin) - Cross-platform (Flutter, React Native) - Backend & cloud (Node.js, Firebase, AWS/EC2, REST APIs) - Payments & marketplaces (Stripe, provider payouts, dual-sided platforms) - AI integration (OpenAI API, Anthropic, Perplexity, and Groq GPT-powered features in mobile apps) - Hardware & connectivity (Bluetooth Low Energy / BLE) - Health & fitness apps (workout tracking, coaching platforms, content programs) What I bring: - A working app on the App Store and Google Play — not a half-built prototype - Clean, maintainable architecture any future developer can pick up and extend - Honest communication: if your budget and scope don't match, I'll tell you up front and help you choose - US-based project management, so you get one point of contact who speaks your language and your timezone How I work: I'm the founder of a small US-based studio. I run your project personally — architecture, scoping, UX, QA, release — and draw on a hand-picked team of developers, designers, and QA engineers for execution. That gives you the oversight and communication of a US contractor with the cost profile of a global team. Typical projects: Marketplace and on-demand apps · health, fitness, and wellness apps · AI-powered mobile products · apps with hardware or payment integrations · greenfield builds from idea to launch · rescue or cleanup of existing mobile codebases. If you have an idea you want built right — or an app that's stuck and needs someone to unstick it — let's talk.
