About Me

Solution Architect with 11 years in IT solution development, deployment, and integration — including 7+ years in banking and financial services (Techcombank, MB, IFIS, Ascend/TrueMoney fintech). I design IT solutions and author comprehensive solution architecture documentation, applying microservice design principles, SOLID, and common design patterns.

I've led core payment and banking systems to successful go-live, with cloud-native delivery on AWS & Kubernetes and end-to-end CI/CD. Hands-on engineer at the core — Java / Spring Boot, ReactJS, and Python — with a growing focus on AI-driven products and AI-assisted engineering.
