Backend Engineer & Agent Developer
Building Backend Systems and Agentic AI Products.
My Focus
I believe in end-to-end engineering — from architecture design and implementation to production operations, owning the full lifecycle. What I build are not demo prototypes, but systems that carry real traffic and survive real failures.
