Work

Production systems across internal platforms and data-intensive apps, plus a couple of AI-integrated products. I own the stack choices and operations along with the implementation. This is a selected public sample. Much of what I've built is client or humanitarian work, kept private.

Featured Projects

NOSBAAN Platform

Event-driven ERP, AI Messaging & Public Portal

Founding Engineer 2025–Present

Founding engineer for an Airbnb Superhost-recognised monthly-rentals operator in Bangkok. I own the platform end to end — an event-driven ERP, a public portal, and an AI-assisted guest-messaging system.

  • Built for reliability: idempotent event processing under at-least-once delivery, failure isolation, and k6-gated releases; the check-in flow ran clean at 120 concurrent, P95 ~1.06s.
  • The messaging system drafts guest replies over RAG behind a grounding guard and human review, so it never sends an unverified answer.

Stack: TypeScript, Go, PostgreSQL, Redis, OpenAI, GCP

MonOCR

OCR for the Mon Language

Solo — side project 2025–Present

An OCR system for Mon, a UNESCO-classified vulnerable language with no prior dataset or toolchain. I built it end to end, from collecting and validating the data to training and deploying the models.

  • Two models (a ~11.4M on-device model and a ~54M server model) deploy across web (WASM), Android (NNAPI), and iOS (CoreML) via ONNX, with a feedback loop that improves accuracy over time.

Stack: Python, PyTorch, ONNX, CoreML, SvelteKit, Go

Civic Data Dashboard for Myanmar

Lead Engineer

A public platform for humanitarian and civic indicators across Myanmar: ~10K active users (2.8K peak daily), ~132K events, 100K+ records. I still maintain it and re-architected its data delivery in 2026 for faster loads on low-bandwidth connections; its identity is kept private to protect the people connected to it.

  • Built on a static-data architecture that compiles Baserow content into versioned JSON, with hybrid rendering per page — fast and cheap to run, with no public database exposure.

Stack: Next.js, GitLab CI/CD, Baserow, GitHub Actions, Puppeteer

Myanmar Biodiversity Portal

Architecture Redesign & Cost Reduction

Lead Engineer 2021–2024

A public biodiversity portal was running create-react-app on a dedicated server, with data split across two systems, for content that changed only a couple of times a month.

  • Migrated to Next.js, consolidated the data into Baserow, and moved most pages to static generation; the dedicated server was no longer needed and the stack got simpler to maintain.

Stack: Next.js, Baserow, PostgreSQL, GeoServer, D3.js, Vercel
