Fullstack engineer · Singapore
I build things,
and some of them
keep running.
Fullstack engineer living in Singapore. I build apps and features, and I like experimenting: a Solana trading bot, a macOS transcription app, an iOS training app, a document pipeline running on a local LLM. All of it built solo, mostly to try out things I wanted to understand, and mostly hosted on a small server in my living room.
Things I have built
Updated by hand, when something changes
Selected work
All 9 →Solana DeFi Trading Platform
A multi-strategy trading bot for Solana: DEX arbitrage, liquidations, keepers and LST spreads. It ran on mainnet with real capital, lost money, and taught me more in that hour than weeks of simulation had.
Hybrid
A training app on the App Store. Type your session as a sentence, import it from Apple Health, and get a score that makes an hour of yoga and an hour of intervals comparable.

The lab
Everything on this site, including this site, runs on a homelab I built and operate: a Proxmox node, a handful of VMs, a local LLM box, and no open ports.
