/ About

I'm a developer who is always thinking of new ideas, constantly seeking opportunities to solve real-world problems through technology. My passion lies in taking these ideas and turning them into robust, well-crafted solutions that are both effective and user-friendly.

Beyond client work, I'm a solo founder — currently building Eroteme, an AI-powered prediction market on Polygon, and Pop the Balloon, a dating app with 1,000+ users on iOS and Android. I'm also a qualified boxing trainer and manage a property portfolio across London, Essex, and Kent.
