Zin Min

Senior Software Engineer

6+ years building and operating production systems end to end: event-driven backends and data pipelines, plus applied ML shipped to production.

Currently Founding Engineer at NOSBAAN, an Airbnb Superhost-recognised monthly rentals business in Bangkok, where I build and run the whole platform. Alongside that, I build MonOCR, an OCR system for Mon, a UNESCO-classified vulnerable language with no prior OCR toolchain. I built it from collecting the data through to training the models.

I also write articles and case studies at vlog.zinmin.com

Selected Work

MonOCR โ€” OCR for the Mon Language

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

Two models (a ~11.4M on-device model and a ~54M server model) export to ONNX and CoreML, with a feedback loop that improves accuracy over time.

Data Platforms

Built a public civic data platform serving ~10K active users (2.8K peak daily), and a separate research platform serving near-real-time policy and research data.

Replaced an Airflow orchestration layer with a lightweight ETL pipeline; data refresh dropped from 1โ€“2 hours to under 5 minutes.

System Migration & Cost Reduction

Led a migration to a simpler system design, cutting infrastructure cost by ~33%. Won team buy-in with a working prototype after showing the existing setup added cost without a matching scaling benefit.

Rebuilt the data pipelines and added backup and recovery, which the previous setup lacked.

Event-driven ERP & AI Messaging Platform

Designed and built the core ERP platform, public portal, and AI-assisted messaging system that powers daily operations at NOSBAAN.

Event-driven: async processing isolates failures and keeps heavy work off the request path. Gated by k6 load tests in CI; the check-in flow ran clean at 120 concurrent, P95 ~1.06s.
