03 / ENGINEERING STACK

The tools I reach for.

“I like understanding what happens underneath the abstraction.”

From thread-safe queues to routing algorithms, I prefer projects that make me reason about the system itself.

04 / ABOUT

Curious by default.
Builder by choice.

I'm a CSE student focused on backend engineering, Java and systems thinking. I enjoy building things that have a little more depth than a CRUD screen — engines, simulations, developer tools and real-time systems.
