AI-Powered Mobile App Developer | Android & Flutter | 11+ Years Experience | Claude Code & Antigravity Agent Mode I'm a full-time freelance Mobile Application Developer with 11+ years of experience building, maintaining, and scaling apps for individuals and businesses worldwide. Over the past year, I've integrated AI-assisted, agentic development tools — including Claude Code and Antigravity IDE (Agent Mode) — directly into my workflow, allowing me to deliver production-ready apps faster, debug complex issues in a fraction of the time, and refactor legacy codebases with far greater precision than traditional development alone. I combine deep Android and Flutter expertise with modern AI-driven tooling to give clients the best of both worlds: the speed and iteration power of agentic coding, backed by 11 years of hands-on architecture, performance optimization, and real-world app maintenance experience. WHAT I BRING Native Android & Cross-Platform Flutter Development AI-Assisted Development using Claude Code & Antigravity Agent Mode Legacy App Maintenance, Refactoring & Performance Optimization Firebase & Third-Party API Integration Application Architecture & Troubleshooting Team Leadership & Project Management I work U.S. business hours for seamless communication and treat every project as a long-term partnership — from first release through ongoing maintenance and growth. I take full ownership, communicate clearly, and use AI tooling not as a shortcut, but as a force multiplier for quality and speed.
