Built from production experience
The content I teach is shaped by real backend systems, not only tutorials or academic examples.
Senior Software Engineer @ Veriff · Ex-Twilio · 10+ years
Learn backend engineering from real production experience.
I write and teach about Java, Spring Boot, Go, Python, system design, distributed systems, databases, Kafka, RabbitMQ, Temporal, Kubernetes, observability, and career growth — helping Bengali developers become industry-ready.

Structured backend learning path
A Bengali-first backend engineering roadmap designed to take learners from Java fundamentals to production-grade backend systems.
Published
Beginner
Java and Object-Oriented Programming Foundation
Build a solid foundation in Java and object-oriented programming through structured lessons, practical exercises, software design, refactoring, and projects. Learn not just how to write Java code, but how to reason about its design and maintainability.
- Published course with 11 modules and 107 lessons
- English lessons with AI-assisted translation options
- Exercises, knowledge checks, and hands-on projects

Advanced
Advanced Backend Engineering
Learn the engineering decisions behind reliable, scalable, and maintainable backend systems. The course follows a production-oriented approach to architecture, data consistency, asynchronous communication, failure handling, observability, and operations. The curriculum is being developed progressively.
- Published course with curriculum released progressively
- Uses Java and Spring Boot as the primary implementation stack
- Built around a distributed commerce platform case study

The Social Media Illusion
I grew up with the internet, from Yahoo Mail and cyber cafes to Facebook, programming, and a career in software. Years later, stepping away from social media taught me the difference between visibility and connection, information and value, and watching life versus living it.
Al-Khwarizmi: The Father of Algorithms
More than 1,200 years ago, Muhammad ibn Musa al-Khwarizmi developed systematic methods for calculation and algebra. Learn how his name became algorithm, how al-jabr became algebra, and why his work still shapes software and computer science.
Success isn’t about the destination, It’s about how far you’ve come
We’re taught to chase big titles, fame, and fortune as the ultimate signs of success. But what if real success is quieter, deeper, and far more personal? A reflection on growth, struggle, and why the journey matters more than the headlines.
