About

Hey, I'm Thanh

I'm a Senior Backend & Cloud Engineer with over 10 years of experience designing and building large-scale distributed systems — primarily in banking, fintech, and enterprise platforms.

My core focus is backend engineering: high-throughput transaction systems, event-driven microservices, and cloud infrastructure on AWS. I've worked across Singapore, Vietnam, and Thailand, shipping production systems that process millions of financial transactions.

Currently at Singtel / NCS in Singapore, where I build cross-border remittance infrastructure and real-time payment processing systems.

Outside of work I'm usually exploring new system design patterns, writing about backend engineering, or looking for the next interesting distributed systems problem to solve.
