Profile

About Me

I am a Database Developer and Data Analyst with practical experience in SQL, Python, ETL, query optimization, stored procedures, BI reporting, Power BI, and database operations. I currently work at Bdjobs.com Limited, where I build data solutions for operational and analytical needs.

Before that, I worked as a Lab Associate at Daffodil International University, supporting students in programming, DBMS, machine learning, OOP, Laravel, practical lab sessions, and project-based learning.

My academic background includes MSc in Data Science and BSc in Computer Science & Engineering from DIU. I am also interested in AI-enabled education, research, n8n workflow automation, Django development, WordPress development, and scalable data-driven systems.
