About Me
Designing and building scalable systems, end to end
I’m a Principal Full-Stack Architect with over 10 years of experience designing and building scalable web platforms. I work across front-end, back-end, and cloud infrastructure—owning architecture decisions and delivering production-ready systems with a focus on performance, reliability, and long-term maintainability.
When I’m not shipping features, I focus on system design, performance optimization, and evolving architectures to scale with growing products. I value pragmatic engineering, clean abstractions, and software that quietly does its job—reliably and efficiently.
