Built in comfort.
Shipped everywhere.

Chittagong, university, a contest hall. Two teammates — CU 413, CU BadToTheBone — five hours on the clock, and problems that did not care how clever anyone felt. We finished 18th at the ICPC Dhaka Regional and won inter-university titles along the way.

Competitive programming taught me the thing no tutorial can: how to stay calm when the clock is loud and the solution isn't obvious yet. Four years of that grind is what cracked my first real interviews and every negotiation since.

I still keep the algorithms repo. Some habits earn their keep.

My comfort zone is a dark room, a terminal, and a problem that refuses to behave. I moved in years ago and never left.

This isn't where ambition goes to sleep. It's where I go when the work has to be right — where deep focus is cheap and pressure is just another input.

Own your territory. Then expand it.

Enterprise microservices that became core revenue engines. A subscription platform serving half a million users. A marketplace where ten thousand providers run their bookings — and cut their manual overhead by eighty percent. Thirty-plus institutions across the UK. A social app in thousands of pockets worldwide.

In 2022 Toptal accepted me as a Verified Expert in Engineering — the top three percent. Since then I've led backend architecture, managed teams, and taken products from an empty repo to a live URL for clients across three continents.

None of that was a demo. All of it went to production and stayed there.

Nineteen articles across LogRocket, Medium, and Dev.to — branded types, state-management benchmarks, GraphQL schema design, cursor pagination that doesn't turn into a mess. Two thousand claps, three hundred followers, and a habit of writing the guide I wish had existed.

In code: zephyr, my open-source time-tracking and invoicing SaaS on SST. Contributions to Flojoy's visual programming studio. Forty-eight public repos going back to 2017, and an Arctic Code Vault badge from the ones that mattered.

Teaching a thing is how I find out whether I actually know it.

Right now I'm building the tooling that trains AI — turning recorded human workflows into structured datasets at SuperAnnotate. Beside it, my repos are full of Rust, Kafka, distributed tracing, RAG pipelines. Standing still has never appealed to me.

The next rung is ownership: products that are mine, revenue that compounds, software that turns ideas into profit without asking permission first.

Eight years in, every title has come with more scope than the last. I intend to keep it that way.
