I build sports and fitness apps on a modern, AI-native stack — using React Native (Expo) on the frontend, and TypeScript + Bun on the backend, with AI agents and gamification driving user engagement. Most sports and fitness apps lose users after only two opens. I specialize in the layer that fixes that: gamification (streaks, challenges, leaderboards, rewards, and social mechanics) combined with AI-driven personalization and coaching — all built on architecture designed to scale fast and efficiently. My edge is the stack I work with: * AI agents using Mastra.ai and Google ADK — for smart coaching, automation, and personalization * AI-assisted development workflows (Claude Code, Codex, Pi) — helping me ship fast, clean, and well-reviewed code * Bun + TypeScript backends — modern, high-performance, real-time APIs * React Native + Expo — one codebase for both iOS and Android * Wearable and sports data integrations, including open-source platforms like OpenWearable The core specialty tying it all together: sports and fitness apps with gamification systems that actually drive daily retention. Recent work includes Fozup — a sports social platform with gamification and marketplace features — along with shipped apps across fitness, booking, and social domains (live App Store / Play Store links below). Top Rated freelancer with 100% Job Success across 20+ contracts. I care about clean code, strong performance, and shipping products without leaving a mess behind. What’s the engagement loop you want users coming back for? Tell me about your app, and I’ll share how I’d build it.

Your backend is either built to scale or built to be rewritten. Most clients find out which one after it is too late. I build production-grade Python backends with FastAPI: structured project layouts, async request handling, JWT/OAuth2 authentication, PostgreSQL with proper query optimization, Redis caching layers, and background task queues with Celery or ARQ. Every system I ship is built to run without babysitting. I have shipped backends for clients across automation pipelines, API integrations, and data-heavy systems. Every project delivered with a 100% Job Success Score and a 5.0 rating across the board. The engineers who build clean backends early are the ones who are not rewriting everything six months later. The ones who do not are the ones posting jobs like this one. Whether you need a greenfield FastAPI service scaffolded the right way, an existing Python backend debugged and hardened, or a data pipeline wired into your LLM stack, I have done it. 100% Job Success Score. Every project delivered.
