Computer Science undergraduate at BRAC University
AI • Backend Engineering • Full-Stack Development • Open Source

I am a Computer Science undergraduate student at BRAC University, Bangladesh, expected to graduate in September 2026.

I build practical software systems across backend engineering, full-stack development, data-driven workflows, and applied AI. My recent work includes a grounded RAG system for codebase understanding, a clinic operations platform, MERN marketplace development, database-backed web applications, and a machine learning thesis on apartment price prediction in Dhaka.

I am also focused on open-source contribution, software testing, Git/GitHub workflows, clean engineering practices, and consistent problem solving.

Pull Request: agno-agi/agno#8582

Undergraduate thesis at BRAC University focused on predicting Dhaka apartment prices using structural and location-based features.

Built a stacking ensemble on 9,167 cleaned Dhaka apartment listings, achieving R² = 0.867 and 14.59% MAPE on a held-out test set, with SHAP interpretability and split-conformal prediction intervals.

Tech: Python, scikit-learn, XGBoost, LightGBM, SHAP

• Solved 700+ algorithmic problems across LeetCode and Codeforces
• Focused on data structures, algorithms, and competitive programming fundamentals
