Hi, I'm Takrimul Hasan.
Java backend engineer, founder, and teacher from Dhaka. I studied CSE at Shahjalal University of Science & Technology (SUST, 2019–2024) after Notre Dame College — and I've been building things ever since.
What I do
I build fintech and SaaS backends with Spring Boot, PostgreSQL, Kafka, and Redis — most recently at TiCON System Ltd on a multi-tenant safety management platform, and before that at RedDot Digital on TeleCash, a fintech platform processing ~$1.6M USD monthly. Outside of work I run a lifestyle brand and teach HSC ICT online — plus I take on client work, building complete digital solutions end to end. All of it feeds each other: engineering gives me the tools, business gives me the stories, teaching keeps me sharp.
What I believe
Skills beat certificates. Shipping beats planning. And Bangladesh has far more talent than opportunity — I want to build some of that opportunity myself, and show students they can too.
