Building for Impact

I architect resilient systems and ship high-performance user experiences. With over 3 years of production-grade experience, I bridge the gap between complex technical problems and elegant, scalable solutions.

From optimizing high-velocity e-commerce engines to engineering complex browser-based 3D design tools, my focus is always on measurable impact and technical excellence.

Dedicated to Node.js, Next.js, and Cloud Infrastructure at scale. Confident in architecture. Intentional in code.
