B.Tech Metallurgy @ KNU · Creator at RejuVerse · Bridging the world of Blast Furnaces & Steel with AI Tools, Digital Marketing & Tech Projects.
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.
BOF, EAF processes, casting, rolling and heat treatment. Understanding microstructure-property relationships in steels.
Metallographic sample prep, hardness testing (Vickers, Brinell, Rockwell), tensile testing and microstructure analysis.
Phase diagrams (Fe-C), crystal structures, defects in metals, diffusion, solidification and corrosion behavior.
Targeting roles in steel plants, quality control labs and R&D. Interested in SAIL, Tata Steel, JSW and leading producers.
Steel is the world's most recycled material — over 1.9 billion tonnes produced annually. India is the 2nd largest steel producer globally, offering massive careers in production, quality & R&D.
