Zin Min

Senior Software Engineer

6+ years building and running production systems: event-driven backends, data pipelines, and applied ML.

Founding Engineer at NOSBAAN, a monthly rentals business in Bangkok. I build and run the platform. Alongside that, MonOCR, an open OCR system for the Mon language.

Selected Work

Event-driven ERP & AI Messaging Platform

Designed and built the ERP, public portal, and AI-assisted messaging system NOSBAAN runs on.

Async processing isolates failures and keeps heavy workloads off the request path. k6-gated in CI, holding P95 ~1.06s at 120 concurrent users.

MonOCR — OCR for the Mon Language

Mon is a UNESCO-classified vulnerable language with no OCR model of its own. MonOCR is the dataset, the models, and the tooling around them.

An 11.55M model exported to ONNX and CoreML, running on web, Android and iOS. Verified samples feed the next training run.
