My Process 💪 Step 1 — Free brief + audit. Send your idea, prototype, Figma files, or existing codebase. As a React Native Developer and Full Stack Developer, I review architecture, scope, risk, and feasibility across mobile and web — no charge, no obligation. Most audits turn around within 24–48 hours. Step 2 — AI-powered prototype. Using Claude Code, Cursor, and OpenAI/Gemini integrations, I build a working, testable React Native or React Next.js prototype in 3–7 days, not months — so you validate real demand before committing to full development. This is the same AI-driven approach that's cut manual workflows by 30–50% and shaved 30–40% off time-to-market on past projects. Step 3 — Build. Full-stack build across React Native Mobile, React Native Expo, React Native Firebase, and web (React, Next.js, Node.js, Supabase/PostgreSQL, MongoDB), with weekly demos so you always know exactly what's shipped and what's next. Sprints run in 1–2 week cycles with clear, measurable milestones — the structure behind 100+ delivered projects and 60+ full production launches. Step 4 — Launch + scale. Deployment (AWS, Google Cloud, or Azure), CI/CD, monitoring, and post-launch optimization — the same DevOps React Native process that's taken apps from 0 to 100K+ MAU, 99.9% uptime, and 5M+ requests/month, while cutting infra overhead by 35% and backend costs by 40%. As a full-stack React Native Developer with 20,000+ hours of hands-on experience across mobile and web platforms, I specialize in React Native, Flutter, React.js, React Native Mobile, React Native Expo, React Native Firebase, React Native WebRTC to build mobile apps.
