Md Sabbirul Islam Khan
SABBiR
Management student building toward Backend & DevOps Engineering, while exploring AI, systems, networking and creative technology.
Where Business Economics Meets Systems Engineering.
I represent a distinctive convergence of business management economics and production-grade software engineering. Currently pursuing a BBA in Management at Rajshahi College, my heart beats in the terminal. I am focused on architecting resilient backend systems, deploying local-first AI pipelines, and mastering the modern DevOps lifecycle.
