I'm a senior software engineer with a track record of delivering robust SaaS platforms and leading transformational engineering initiatives. Over a decade at industry leaders like Stripe and Vercel, I’ve owned the most complex challenges in the stack, built scalable architectures, and elevated team velocity. I don’t just write code—I set engineering direction, design scalable systems, and accelerate delivery across product, design, and growth teams. This work is my craft: rebuilding core products, modernizing legacy infrastructure, and shaping roadmaps with product teams. I bring deep technical vision, product intuition, and uncompromising craftsmanship to every line of code, every system decision, and every collaboration. I’m the engineer people turn to when something has to be done right—the first time.
