About

Profile

I like building tech that creates real positive impact on society.

Before university, I scored 44/45 on the IB Diploma at NPS International School and ranked #1 globally out of 52,000+ candidates in Cambridge IGCSE Mathematics.

I served as a firefighter with the Singapore Civil Defence Force.

At other times, you'll find me playing guitar, the bansuri (Indian bamboo flute), or on the pitch playing football.

YearnOut

Turnout alerts that cannot be missed.

A dispatch-alert system for firefighters, built end to end. When the station turns out, every crew member's phone rings like an incoming call — full-screen, over silent mode — instead of a mutable notification.

Beyond Code

After hours

Guitar

Been playing for 13 years, both acoustic and electric, and I post occasional covers on YouTube. My favourites are John Mayer, Kenny Rogers, and Arijit Singh.

Bansuri

The Indian bamboo flute — I taught myself four years ago, and I like playing Sufi songs on it.

Football

I play at Singapore Football Club, competing against professional men's and youth teams across Singapore. I captained my school team to our first championship title in five years.

Hiking

I've summited Mount Agung at sunrise and trekked to Tiger's Nest on its Bhutanese cliffside. I like the quiet up there — a few hours on a trail resets me better than anything else.

Coin Collecting

I collect coins that tell stories — 19th-century British silver my granduncle found in our village in Maharashtra, Mughal copper, North Korean won, Tibetan exile currency.

Firefighting

I spent two years as a firefighter with the SCDF, responding to fire, rescue, and medical calls across Singapore. Easily some of the most meaningful work I've done.
