About

I'm Tran Vinh Vu, a backend and cloud developer with 20+ years of experience building and operating production web systems — Java / Spring Boot microservices on AWS, e-commerce platforms, and API integrations for aviation, banking, media, and e-commerce clients.

Obiz Solutions is where I share notes on the systems I've built and the lessons learned along the way, and where I take on custom software work.

What I work with

• Languages & backend: Java 8–21, Spring Boot, Spring Security, Spring Data JPA / Hibernate, Node.js
• Cloud & DevOps: AWS (EC2, Lambda, S3, API Gateway, CloudFront), Terraform, Docker, Jenkins, GitLab CI/CD, GitHub Actions
• Data: PostgreSQL, MySQL, Oracle, MS SQL Server, MongoDB, Elasticsearch
• Architecture: microservices, Keycloak / OAuth2, API design, load testing

How I work

Based in Vietnam, working remotely with clients across time zones — either owning a project end-to-end (development, infrastructure, CI/CD, security) or joining a distributed team as a principal developer or technical architect.

Background

• Bachelor of Science in Information Technology, University of Natural Sciences, Vietnam National University – Ho Chi Minh City (2001)
• Sun Certified Programmer for the Java 2 Platform 1.4 (2007)
