About

I build reliable APIs, automation pipelines, and AI-enabled products that turn complex workflows into simple, scalable systems. I am most interested in backend engineering because I like building the core systems that make products dependable, secure, and scalable. At the same time, I enjoy integrating AI when it genuinely improves the user experience or product capability rather than adding hype. A lot of what I build comes from real problems I have lived through or seen people around me struggle with, like finding opportunities, navigating school and career systems, and getting access to the right information at the right time. My goal is to ship useful software that saves people time, reduces friction, and makes systems more accessible.

Experience

Recent roles focused on APIs, data pipelines, performance, and systems that hold up under real usage.
