About Me
Hi there! I'm Bùi Thế Sơn, a Mobile Developer with over 12 years of deep experience in iOS and Flutter.
My journey started in 2013 with Objective-C, going through outsourcing, building my own startup (ShipDauRoi - Top 50 App Store VN), developing a global platform for Pizza Hut, and currently building health tech apps at Jio Health.
I believe in sharing practical knowledge - not just theory, but lessons learned from shipping real products and serving real users.
