About me

I identify as a Developer with a Product-oriented mindset.

Android app development has been my passion since my student days. I'm drawn to its widespread use, continuous improvements by Google, and its ability to quickly adapt to new technologies.

In my initial role at EA, I worked as a Fullstack Developer. demonstrated my ability to learn and adapt quickly by working with Python/Django framework. During my time at EA, I made significant contributions to two Django projects, working in collaboration with the team and independently completing a data project, which gave me a well-rounded understanding of end-to-end system processes, covering backend, frontend, database management, and cloud services.

Seeking a fresh challenge, I joined 25 Inc., a Startup company, as its first member. I played a pivotal role in developing our first product: gannha.com app. Over time, we've brought numerous concepts to reality, consistently enhancing the original version, and expanding our team to include iOS, Backend, and Data specialists. Working in a startup has afforded me the opportunity to do more than just programming; I've also played an active role in shaping product strategy, giving new ideas, and managing partner relationships, services, and administrative tasks.

Recently, I started contributing to a well-known platform from Viet Nam - the Zalo app. We keep the product stable for millions of users, keep them up-to-date with new features along with solving performance challenge.
