“I had the pleasure of working with David during our time at SkyGo, and later on a separate project called AirUI. Throughout both engagements, David consistently demonstrated the qualities of a well-rounded and highly capable software developer. David brings a deep and diverse programming skill set to any team. His proficiency spans across Java, Kotlin, Dart, and C, among other languages, allowing him to contribute effectively across a wide range of technical challenges. Whether working on mobile platforms, backend systems, or cross-platform solutions, David approaches problems with clarity, creativity, and a strong analytical mindset. Beyond his technical expertise, David is a collaborative and dependable team member. He communicates clearly, supports his peers, and consistently delivers high-quality work on time. His professionalism and positive attitude make him a valuable asset in any development environment. I highly recommend David for any software development role. He would be an excellent addition to any team looking for a versatile, thoughtful, and technically strong developer.”

Senior Android Developer @ Sky
“I worked closely with David during our time at Sky. I initially heard about him from others as “this great coder who had left our team”, but later I had the chance to personally get to know him and to discover many great components and features he had designed. His code was easy to read and, to this day, serves as the foundation for a shared video-streaming library at Sky. David’s passion for coding makes him one of the most hard-working people I have had the chance to meet. He is constantly learning new things and sharing his knowledge with others. He is also comfortable challenging the status quo to improve both products and processes. I have seen this a few times while at Sky when he proposed different technologies stack that led to better products. I would trust David with any project that needs to be brought to life and built for maintainability and long-term success.”

Android App Architecture Unit Testing Software Development Motivation Impostor Syndrome
It's not a motivational book. It's not about positive thinking or manifestation or hustle culture. It's about a simple, liberating truth: nobody is watching you fail. The audience you imagine, the one judging your every move, doesn't exist. Everyone is too busy worrying about their own lives to scrutinise yours. And once you really understand that, you're free to start. Start ugly. Start scared. Start before you're ready.
