Builder at the intersection of product thinking, data science, and simulation.
I build tools for people who can't afford to get it wrong - solo founders, small operators, families navigating real financial and operational decisions in SEA markets that Western tooling consistently ignores.
I do technical work not because it's all I can do.
I do it because I enjoy it.
Open infrastructure layer
Lightweight observability for solo builders.
Structured data extraction from messy real-world SEA documents - mixed language, informal, non-standard.
Voice-to-data pipelines for SEA languages.
On-device model optimisation for median SEA Android hardware.
Product layer
Envelope Lite - personal finance tracking for the SEA market, built around behavioural habit formation rather than feature complexity.
Simulation layer (in development, private for now)
Tools that answer one question before you commit:
"You don't know how it happens - let me show you first."
Workflow simulation for small operators.
Game theory simulator - accessible, visual, runs in the browser.
Operational simulation for small businesses starting with food service.
Problems before solutions. Always.
Kill criteria are set before any experiment starts.
SEA market realities are not the Western market realities with a different flag.
Simulation over assumption wherever possible.
Data science studied properly - foundations first, the pioneer level is the destination.
The open infrastructure repos fund trust.
The product layer funds survival.
The simulation layer is the long game.
All three are active. All three are connected.
Vietnamese. Building for SEA. Honest about what's still being built.
