About
I architect AI-powered systems and automation tools. From real-time chat infrastructure handling millions of messages to intelligent agents that work for you—I build systems that scale and solve real problems.
I believe in understanding technology at its core. Whether it's 3D printing, mobile engineering, or cutting-edge AI, I dive deep and build tools that make life simpler. If it can be automated, I'm probably already working on it.
I hack on everything from AI and mobile apps to Web3, always pushing the boundary of what's possible with code and shipping fast.
