I’m a backend developer who builds reliable PHP/Laravel APIs and turns complex requirements into working systems. I’m based in Vietnam (Ho Chi Minh City) and I’m ready for remote work, with 11 years of hands-on experience.

In recent projects I develop APIs on Laravel (jsonApi, GraphQL, RESTful), integrate with external services on the backend, and support frontend work when needed. I enjoy clean architecture and maintainability—applying SOLID, DRY, KISS and proven design patterns while delivering features fast.

I also bring strong engineering depth: Linux/Ubutu server setup, Nginx, Docker/Docker Compose, CI/CD for production deploys, DNS/SSL, and unit/feature testing. I’ve built real-time web-socket chat features (including ChatGPT prompt-based flows) and even a non-commercial blockchain API in Go with Vue-based tooling.
