About me

Engineering with ownership, clarity, and depth.

I enjoy solving problems that go beyond isolated feature work. Whether it is designing a backend architecture, building internal utilities, handling server infrastructure, or mentoring team members, I like being involved where the solution really takes shape.

I focus on reliability, maintainability, and scalability while keeping delivery practical for real business needs.

Execution

From whiteboard to deployment

I’m comfortable moving across backend, frontend, infrastructure, and operations to get meaningful work shipped.
