Hi, I'm Phu Dung 👋
I build products and digital systems at the intersection of Business × Technology.
From an Economics background to becoming a Fullstack Developer, I am constantly driven by one question: “How does this technology genuinely solve real problems for people and businesses?”
From Economics to Lines of Code
I didn't start my career with a Computer Science degree. Born and raised in Da Nang, Vietnam, I graduated from the University of Economics – The University of Da Nang (DUE). Those academic years gave me a solid foundation in market dynamics, cash flows, business operations, and efficiency optimization.
If someone had told me a few years ago that I would spend most of my days designing database schemas, architecting APIs, customizing CRMs, and engineering scalable systems — I probably wouldn't have believed them.
My journey took an exciting turn when I joined the international team at Pure Electric. There, my manager and mentor – Matt – recognized my potential and generously supported my transition into professional software development. From those first lines of code to officially engineering production systems for Pure Electric, it was a defining milestone in my career.
Following Pure Electric, I embarked on a journey as a Freelancer & Software Builder. I worked on a wide range of real-world projects — from CMS and E-commerce platforms to custom CRM and ERP systems for diverse business models. Combining business intuition with engineering capability allows me to look at technical challenges through the lens of operational efficiency and tangible business value.

My Working Philosophy
Technology exists to solve real problems
I don't adopt technology simply because it's novel or trending. The best technology is the one that solves the underlying problem sustainably and effectively.
Understand the business before writing code
A great system never starts with a database schema or a trendy framework. It starts with a thorough understanding of how the business operates and delivers value.
Never stop learning, never stop building
Technology constantly evolves. What matters most is not knowing everything upfront, but preserving an insatiable curiosity and the joy of creating something new.
