B.Sc. Computer Science and Engineering · North South University · 2015–2019 · Dhaka, Bangladesh

My Journey

From a CS degree in Dhaka to ML in production and agents that ship — the chapters in between.

  1. 2015

    Foundations

    North South University · Dhaka, Bangladesh

    A B.Sc. in Computer Science and Engineering. Four years of algorithms, systems, and the first real code that had to run — not just compile.

    The degree closed. The first internship opened a hardware door.

  2. 2018

    Hardware meets software

    Py Labs · Dhaka

    A frontend for bulk SMS, and a Raspberry Pi with a GSM module that actually sent the messages. The first time software had to talk to a radio.

    From a Pi on a desk to enterprise portals in the cloud.

  3. 2019

    Enterprise, in production

    Codemen Solution Inc. · Dhaka

    Attendance tracking and housing management portals — React, Node.js, Express. Secure REST APIs and SQL that had to stay fast under real users.

    Cloud apps taught me reliability. Semiconductors taught me scale.

  4. 2020

    Inside the fab

    GlobalFoundries · Contractor

    Internal web apps and analytics for semiconductor manufacturing. Staging and production, Perforce and Git, datasets measured in millions of records.

    Two years of manufacturing data. Then the stack got wider.

  5. 2023

    Full-stack, then models

    Teton Private Ltd. · Dhaka

    Software Engineer II. React, Node.js, Django, Laravel, Python — and TensorFlow models for predictive analytics, wired into Django REST so the dashboard could show what the model saw.

    Models in production. Next: agents that act on their own.

  6. 2025

    Agents, and a scoreboard

    Synopsys · Contractor · via Teton

    PinCheck Dashboard: a Python QA scoreboard that replaced spreadsheets for pin-interface validation — YAML parsers, Perl reruns, SQLite snapshots, ~96 hours saved per release. In parallel, LangChain agents that watch e-commerce deals and fire alerts on their own.

    Seven years in: full-stack, ML in production, and agents that ship.

08 Let’s Connect

Let’s create what’s next.

I’m open to software engineering roles, collaborations and good conversations — full-stack, ML, agentic systems. If you’re building something that has to run, I’d like to hear about it.
