About

I'm a software developer with over 7 years of experience building secure, scalable digital banking solutions. Most recently, I spent 7 years at BCEL (Banque pour le Commerce Extérieure Lao), the largest commercial bank in Laos, where I led the development of mission-critical financial systems.

During my tenure, I pioneered the first cardless cash withdrawal system in Laos, built real-time customer support systems that increased efficiency by 430%, and led the modernization of payment infrastructure serving thousands of merchants nationwide.

I work across the full stack—from building responsive frontends with Svelte and Vue, to architecting backends with Node.js, Java, and Spring, to managing cloud infrastructure on AWS. I have extensive experience with CI/CD pipelines using Jenkins and maintaining high-availability systems with the Elastic Stack (Elasticsearch, Logstash, Kibana) for monitoring and log analysis.

When I'm not coding, you'll find me on the basketball court or soccer field, staying active and enjoying team sports.
