I am a UK-based freelance iOS & Android app developer and consultant, developing cross-platform native mobile apps for iPhone, iOS, iPad, Android and the Web. Jason Kneen
I develop cross-platform native apps for iPhone, iPad, iOS, Android and Windows Phone using the Appcelerator / Axway Titanium SDK, React Native, and Flutter. I work with startups, SMEs and corporates all over the world -- either developing a new app or working as part of a team on existing projects. I also work as a consultant, assisting in developing prototypes, wireframes, requirements and even helping pitch to investors. Occasionally I do some .NET and Classic ASP web development. In addition to development I also speak at conferences all over the world on cross-platform native development. If you have an app idea for IOS or Android, you're an individual, startup or SME / corporate, then please get in touch.
