About

Software engineer with a strong foundation in backend systems — Java, Spring Boot, microservices — and the curiosity to go fullstack when the product demands it.

I'm drawn to work where engineering and AI intersect: building systems that are reliable, scalable, and genuinely useful to the people who use them.

Currently deepening my work at the intersection of product and infrastructure, with a focus on AI-integrated applications.
