In my own words
I represent a distinctive convergence of business management economics and hands-on software engineering. Currently pursuing a BBA in Management at Rajshahi College, my heart beats in the terminal. I am focused on building reliable backend systems, experimenting with local-first AI, and learning the modern DevOps lifecycle.
Based in Rajshahi, Bangladesh, I explore Backend Engineering, DevOps, Local AI (such as Ollama), Linux, and IT Systems. I believe in learning by doing, which has led me to build projects like Omnidesk BD and contribute actively as a Google Maps Local Guide. You can find my open-source work on GitHub or connect with me professionally on LinkedIn.
