I'm a full-stack engineer based in Phnom Penh, Cambodia, with 18+ years of experience building software across mobile, web, and desktop — for banks, factories, schools, and beyond. I care about clean architecture, developer experience, and shipping things that actually work.
What I build with, end to end.

ASP.NET Core portals and NestJS APIs powering enterprise workflows at scale.
Rich Windows apps in C# with MVP pattern — payroll, POS, HRM, and more.
Next.js & TYPO3 sites with SSR, i18n, PWA, and Tailwind-polished UIs.
MSSQL, PostgreSQL, Redis, and DynamoDB — schema design to query optimisation.
Docker, GitHub Actions, AWS ECS/S3/RDS — CI/CD pipelines from code to cloud.
Figma-to-code design systems, glassmorphism, and responsive Tailwind interfaces.
End-to-end delivery with Jira, GitHub Projects, and agile sprint planning.
SAST, SCA, Secret Scanning, Image Scan, SBOM, and IaC scanning in every pipeline.
Tools and platforms I work with daily.
