About

I specialize in systems modernization, digital transformation, and scalable web architecture — from monolithic PHP to full-stack Node.js (Nuxt 4). I've shipped platforms handling ฿92M+ annual transaction volume across 90+ retail branches with financial accuracy, built Oracle ERP sync pipelines (AR Invoice / AR Cash Receipt / Credit Note), integrated T2P QR Code payment gateways, and tuned MSSQL/MySQL/PostgreSQL for lock-contention prevention under high concurrency.

A Zero-to-One Technical Leader — I build backend architectures from scratch and modernize legacy systems end to end. Based in Pak Kret, Nonthaburi, Thailand. Targeting Senior Full-Stack / Technical Lead roles — On-site, Hybrid, or Remote.
