About

Francis Bergonia, also known as Jay, is an entrepreneur and developer passionate about turning ideas into real-world products. As a software engineer, I've worked across industries like banking, IoT (smart home devices), and healthcare — designing and building projects that solve real problems. With over 8 years of experience in mobile app development — through employers, freelance work, and my own startup Xi Apps — I've delivered dozens of apps, primarily using Swift, along with experience in Flutter and web technologies. I’ve also led teams, mentored junior developers, and handled project coordination. Outside of work, I stay curious — keeping up with the latest in mobile development, exploring new tech, and sharpening my coding skills.
