About

Hi there

I'm Bui Thanh Tung [alias TungDaDev or Vincent at work], a software engineer from Vietnam. I have a passion for all things Java & backend development. I enjoy building financial software and stuff related to web dev. I work mainly with Java, Kotlin, TypeScript, JavaScript, Python, SpringBoot, Spring AI, React.js, Node.js, Next.js, Agent AI, MCP.

This blog serves as a journal for documenting and sharing the insights and knowledge I've gained as a software engineer. Building, learning, writing and sharing things is a great way for me to solidify my understanding of new concepts and ideas.

I would greatly appreciate any comments and thoughts on my posts .
