Phạm Đình Khôi Văn

Hi! I'm Pham Dinh Khoi Van, a Senior Android Developer with over 8 years of experience specializing in mobile banking applications. Currently, I'm working at VietinBank, one of Vietnam's largest banks, where I lead the Android team for corporate banking solutions.

Throughout my career, I've contributed to mobile banking solutions for most major Vietnamese banks including VPBank, HDBank, Agribank, CPBank, SGBank, and ABBank. As a key member of the Agribank OMNI project, I helped deliver one of Vietnam's largest digital banking transformations, serving millions of customers nationwide.

As a Senior Developer, I focus not only on writing clean, maintainable code but also on mentoring junior developers, conducting architecture reviews, and making critical technical decisions. My deep passion for Android internals - from custom ROMs to system-level optimizations - enables me to design high-performance, secure solutions that meet the stringent requirements of banking applications.

Outside of work, I enjoy challenging myself through sports like football, running, and especially trail running. This blog is where I share technical insights, lessons learned, and stories from my journey as an Android Developer in Vietnam's dynamic fintech landscape.
