About Me

6 years building software where failure isn't an option - airport terminals, enterprise platforms, and AI products that ship.

I'm a Senior Full Stack Engineer with deep expertise in Angular, TypeScript, React, and cloud-native AWS architectures - building mission-critical software from real-time airport check-in systems at Delta Air Lines to AI-powered automation platforms at Hashedin by Deloitte.

I care deeply about engineering quality - clean architecture, performance, and systems that scale gracefully under pressure. I take complex problems, break them into clear structures, and deliver software that actually moves the needle.
