About Me

Shahu Wagh

I'm a Computer Science student at the National University of Singapore, passionate about building AI-native products.

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

Currently serving as a Firefighter with the Singapore Civil Defence Force, I've learned to stay calm under pressure, work as a team, and make quick decisions — skills that carry over into everything I do.

When I'm not building or responding to emergencies, you'll find me playing guitar, the bansuri (Indian bamboo flute), or on the field playing football.

Beyond Code

There's more to me than algorithms and APIs

Guitar

Guitar

I've been playing for 13 years now — it's how I decompress after a long day. I love blending Indian music with distortion, kind of my own Hendrix-meets-Hindustani thing. I occasionally put up covers on YouTube and am completing Grade 8 Trinity.

Bansuri

Bansuri

I taught myself the Indian bamboo flute. Four years in, it's become my way of staying connected to my Indian roots while living in Singapore — there's something beautiful about the soothing sound of the bansuri.

Football

I play at Singapore Football Club, competing against professional Men's and Youth teams across Singapore. I also captained my school team, leading us to our first championship title in 5 years.

Hiking

Nothing clears my head like a big climb. I've summited Mount Agung in Bali at sunrise, trekked to Tiger's Nest monastery clinging to a Bhutanese cliffside, and I'm always chasing the next trail. Mountains remind me how small my bugs really are.

Coins

Coin Collecting

This one's nerdy even by my standards. I collect coins that tell stories — 19th-century British silver coins my granduncle found in our village in Maharashtra, Mughal copper coins, North Korean won, Tibetan exile currency. Each coin has its own profound mysterious story.

Firefighting

Serving with the Singapore Civil Defence Force has been the most humbling experience of my life. Running into burning buildings, rescuing people from catastrophes, doing VVIP standby at the Shangri-La Dialogue — it has taught me a lot about working under pressure.
