05 — Full Circle

Back where it started.

"Excited to share that I was invited as an industry expert in the grand viva of National Institute of Technology, Agartala's Chemical Engineering Department. Returning to the halls that nurtured and molded me — this time as an industry expert examiner — was a nostalgic and fulfilling experience. Grateful for the chance to give back and engage with the students and faculty."

06 — Beyond the Boardroom

Off the floor.

Outside of engineering drawings and plant metrics, I have a deep appreciation for precision craftsmanship, creative narrative structure, and exploring regional heritage.

I'm an avid enthusiast of horology and vintage mechanics — valuing the intricate engineering of classic timepieces. My creative outlets include long-form fiction writing, where I apply the same structural discipline found in industrial engineering to complex, fast-paced world-building — alongside exploring diverse culinary traditions and distinct regional flavour profiles.
