I'm Nisan Hossain

I’m Nisan Hossain, a backend-focused Software Engineer passionate about building scalable, secure, and high-performance web applications. I specialize in Python, Django, and the Django REST Framework (DRF) — with strong experience in backend architecture, API design, authentication systems, and database-driven development.

My approach to engineering emphasizes clarity, structure, and reliability. I enjoy designing well-organized systems, optimizing performance, and building backend logic that is predictable, maintainable, and production-ready. I’m deeply interested in system design, database modeling, and solving real-world backend challenges.

I have a strong foundation in C, C++ (Data Structures & Algorithms), Python OOP, MySQL, PostgreSQL, REST APIs, role-based authentication, and modern backend workflows. My development process typically includes designing clean API endpoints, creating efficient database schemas, and ensuring smooth integration across systems and services.

I’ve solved over 840+ competitive programming problems, which strengthened my logical thinking, optimization skills, and algorithmic understanding. Some highlights include:

• 420+ problems on Codeforces (Max Rating: 1062)
• 180+ problems on LeetCode
• 2★ Coder on CodeChef (Highest Rating: 1441)
• 135+ contest & topic-based problems on Vjudge
• Additional problem-solving on HackerRank

These experiences helped me develop a sharp engineering mindset — enabling me to write optimized queries, design efficient endpoints, and understand complex backend logic confidently. I constantly learn new technologies, improve my architectural skills, and explore best practices for building scalable systems.

I’m always open to collaboration, backend-focused discussions, and building impactful software solutions with clean, reliable engineering.
