I build systems that execute. I write essays that unsettle.
Mostly, I sit here — breathing.

01 — Manifesto

A BCA student who wrote a Unix shell to understand how processes live and die.
Who built a distributed engine to understand how systems scale.
Who writes essays to understand why we pretend any of it means something — and then, why it does.

I am not a product of my transcript. A 5.8 CGPA says almost nothing about the 500 REPL iterations I ran until my shell stopped leaking. It says nothing about the night I fought CORS, mixed content, and a 1GB RAM ceiling until a VM in Azure began answering to my name.

I read Nietzsche the way some people scroll. I lift weights the way some people pray. I solve LeetCode problems the way a monk counts beads — not for the number, but for the attention.

— the short version

I build for early-stage rooms where one person can ship a backend, a worker queue, a reverse proxy, and a frontend before lunch. I don't want a bootcamp-shaped career. I want a craft-shaped one.

My long game is quiet: earn enough from code to choose a small, grounded life — a house with a garden, a sibling who doesn't have to worry, essays that outlive the algorithm that hosted them.

Until then — I sit here. I build. I breathe.

A distributed code execution platform. FastAPI talks to Celery, Celery talks to Docker, Docker runs untrusted code inside a 1GB VM that shouldn't be able to hold all of it. It does.
