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 7 →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.
Voxa
Signed · v1.2.1A native macOS app that transcribes and diarizes meetings entirely on-device. Signed, distributed, and used every day for two hundred meetings.
DocStack
No public repoA self-hosted document pipeline: OCR, a local LLM, and an entity graph that builds and resolves itself. No document ever leaves the house.
Also built
- Health DocsPhotograph a medical document and it comes back named, filed, attached to the right episode of care, with the personal summary already rewritten. A local model does the reading, on a machine at home.8 model calls per document →
- WhatToWatchA trailer feed you scroll through one film at a time, filtered down to what your own subscriptions can actually play. Running on my own server, with a public URL.Open →
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.
