WHOAMI

I'm a backend engineer and 2026 CSE graduate. I mostly work on backend-heavy products and the system logic that makes them hold together.

I started taking software seriously in 2023, moving from rebuilding existing projects to shipping ideas of my own.

I like projects that get complicated before they get good. I keep working through the details after the first version works.

Right now I'm building AgentProof and Agent Playground while going deeper into system design, CLI tooling, and code review systems.
