About
Most software gets built twice: once cheap and fast to prove the idea, then again — painfully — when it actually works. I build the first version like it has to last, because if your idea works, it does. I'm a full-stack engineer who partners with founders on the products they're betting the company on — SaaS platforms, B2B tools, and long-haul ideas that only pay off if the code can grow with them. TypeScript, React, Next.js, Node, and cloud: used not to show off a stack, but to ship something your users trust and your future team won't have to tear out.
