About

Engineer, Builder, Author

I am a Bangladeshi engineer working across the full stack — from embedded IoT hardware and native Android apps to Node.js and React products — with a research practice focused on explainable deep learning for medical imaging and network security.

My undergraduate thesis at RUET produced BOIMELA, an EPUB3 reader with a multilingual e-book store, an OAuth 2.0 API and an MVVM architecture. Since then I have led client work at Qubitech Solutions, published nine peer-reviewed papers, and won international project awards including IEEE YESIST12 2020 (Special Track winner).

  • 14 shipped projects spanning mobile apps, back-end APIs and web platforms
  • IELTS 8.0 and GRE 301 — official reports available to download
  • Open to software engineering roles in Bangladesh and overseas
