    Founder & Lead EngineerPrivatian (opens in a new tab)

    Privatian helps students get into private universities in Bangladesh with live online courses, exam batches and printed prep books. I built the whole platform alone, from the database up, and run everything.

    • Rebuilt the platform from WordPress on Next.js, Express, PostgreSQL and Redis
    • Automated enrolment: buying a course adds the student to every class in its routine on the Google Meet calendar, so only enrolled students can join
    • Built Google Classroom-style teacher tools for materials, quizzes, routines and assignments
    • Device fingerprinting and device-ID limits per student to stop piracy
    • Live classes that play on phones, tablets and computers, with bKash checkout

About

From gaming videos to production software

I started online in 2017 as a gaming YouTuber. My channel, Technomoni, grew to about 95K subscribers and brought partnerships with Codashop, Tencent, Garena and Booyah, plus brand work with realme and Grameenphone. Building an audience taught me what people actually use, long before I wrote production code.

In 2022 I started Computer Science & Engineering at North South University and, the same year, founded Privatian, an admission-prep platform I built on my own that has sold around 10,000 courses. Since then I've built Dopamine Drops BD for a client, an e-commerce store with 550+ orders and automated SMS and Telegram alerts, and a school management system with an RFID gate box I built, now in daily use at the kindergarten I grew up in.

How I work

The same loop, every time.

  1. Sit with the actual operation

    Before writing anything, I watch how the work really runs: who takes the order, who marks attendance, who collects the fees, and what happens when the internet drops.

  2. Ship the smallest useful slice

    A working checkout beats a beautiful dashboard nobody can trust. Get it in front of real users early.

  3. Harden what people depend on

    Payments, permissions, device limits and the alerts that tell someone when it matters. The boring work is what keeps the product alive.

  4. Count it, then write it down

    Every number on this site is real. Claims without receipts don't belong in a portfolio.

Beyond the code

Travel and languages

I love travelling, and my dream is to see the world on a full world tour.

I took my first solo international flight in 2019, when I was just 16. So far I've been to India, Malaysia and Thailand, travelling to Malaysia and Thailand on my own, and I shared the trips as vlogs on YouTube.

Travelling is how I learn other cultures and languages. I'm comfortable in Bangla, English, Hindi and Urdu, and I'm learning German to make it my fifth language.
