Hai Long Nguyen

Backend Developer focused on building scalable, production-ready systems with Java (Spring Boot). I design clean APIs, optimize databases, and ensure high performance under real-world workloads.

I also bring DevOps capabilities — Docker, CI/CD pipelines, Linux server deployment, and cloud hosting — allowing me to handle projects from development to deployment without friction.

Comfortable working remotely and tracking hourly productivity. If you need a reliable backend engineer who delivers clean code and measurable results, I’m ready to contribute.
