Full-stack developer · Helsinki, Finland

Nazmul
Haque Khan.

I turn messy requirements into deployed, considered products — modelling the system, designing the service, shipping the code.

React & TypeScript on the front, FastAPI & PostgreSQL behind it, and a service-design habit of starting from the user. Currently finishing an MSc in Software Engineering at LUT University.

About

A developer with a design-driven approach — from clear requirements and system modelling through to deployed, production-quality software.

My toolkit spans React, TypeScript, FastAPI and PostgreSQL, with deployed projects like Kirjastokaveri serving real Finnish users. I lean on service design and UX research to keep solutions genuinely user-centered, and reach for Python — Pandas, NumPy, Scikit-learn — when the answer lives in the data. After a decade leading service teams, I bring a calm, dependable way of working to every project.
