About Me

I build full-stack web apps and AI tools that solve real business problems.

As the founder of Ceramic Catalysts, I've delivered high-performance portals and AI automation tools for 42+ clients to help them eliminate bottlenecks. Over the last 12 months, I've independently architected and shipped 4 production-grade applications from scratch.

AI is my core engineering partner. By building alongside advanced AI models, I ship clean, production-ready code in a fraction of the traditional time. You get your product faster, without sacrificing quality.
