Md Sanwar Hossain profile picture

Hi! I'm Md Sanwar Hossain

A passionate Full Stack and Backend (Java) Developer and AI Enthusiast exploring Agentic AI, LLMs & Intelligent Systems, with almost 2 years of professional experience building scalable, secure, and high-performance enterprise applications. I'm currently completing my B.Sc. in Software Engineering at IIT, NSTU, while working as a Software Engineer at BRAC IT SERVICES LIMITED—where I started as an intern and progressed through continuous learning and impactful contributions.

What I Bring to the Table

  • Build robust backend systems using Java, Spring Boot, and RESTful APIs
  • Develop dynamic, user-friendly web applications with React and Angular
  • Design optimized database schemas, write efficient queries, and manage complex data flows in PostgreSQL
  • Implement microservices architectures, CI/CD pipelines, and cloud-ready deployments
  • Use Docker to streamline environments and improve scalability and performance
  • Deliver clean, maintainable, and production-ready code following SOLID, TDD, and Agile practices

At BRAC IT, I've worked on multiple live ERP procurement and tender management modules for large organizations such as BRAC and Plan International, gaining strong experience in real business workflows, system optimization, and enterprise-grade solutions.

In my final academic semester, I conducted research on technical debt in AI-generated code vs. community-driven solutions (e.g., Stack Overflow)—gaining insights into code quality, maintainability, and sustainable software design.
