About Me
#
I can work both in Bangkok and Rayong. I’m a Software Engineer with hands-on experience building enterprise-grade backend systems & APIs. I completed a 7-month co-op internship at SCB — one of the largest banks in Thailand — where I was part of the EAPI team and took on responsibilities in microservices, event-driven Kafka pipelines, and developer tooling used in live banking operations.
Beyond banking, I also built and maintained large-scale game server infrastructure at MineStar: managing 30 dedicated servers supporting 3,000 concurrent players, with automated provisioning using Ansible and infrastructure monitoring through Grafana & Prometheus, maintaining 95% uptime.
My senior project, Craftify, won the IT D-Day 2026 Award. I’m skilled in Java & Spring Boot for Backend development, as well as Next.js and Svelte for Frontend development, with a strong focus on Backend Engineering and Infrastructure. Currently seeking a full-time Backend or Fullstack position.
