Software Engineer

I build tools that make developers faster and help startups grow. I specialize in building agentic workflows, oss infrastructure, high-performance web systems, and creating technical content. I've spent years building products used by thousands, from developer-facing infrastructure at Keploy and Wizdom to building the user base for early-stage startups. My work sits at the intersection of agentic AI, open-source ecosystems, and growth engineering.
