Lead iOS Developer & Entrepreneur

@D App Online Ltd

London, UK

I'm an entrepreneur and lead developer at D App Online Ltd. I created D App Online to publish my apps. I design and prototype UI/UX mobile and web apps through to production-ready applications ranging from business apps to games. I have a great interest in the latest technologies and a keen interest in augmented reality (AR) and machine learning. I've worked in the IT industry for over 20 years and have been developing iOS apps for last 4 years. I consider myself a problem solver, whether that's solving problems in my own life or in my professional life, it does not matter as the methods for solving problems are the same. Being inventive is my trait and I like to incorporate this into the work that I do with passion. During my time developing I have successully launched 7 apps on the App Store.
