About Me

Student. Creator. Builder.

I'm Reju Hosen, a B.Tech student in Metallurgical & Materials Engineering at Kazi Nazrul University, Asansol (Batch 2024–2028), currently in 3rd Year, 5th Semester.

I run RejuVerse — the #1 YouTube channel at KNU, covering WBJEE guidance, campus life & student help content.

My world runs on two tracks — Metallurgy (steel making, heat treatment, quality inspection) and Tech & AI (Python, digital marketing, content creation). Building Reju's Jarvis — a voice-controlled AI assistant in Python.
