    Rhys Leo Coronado Agency Contractor

    Mobile App Development Specialist

    Philippines - Last active: 1 month ago - Tests: 2 - Portfolio: 1

    Rhys is considered as a Jack of all Trades, Master of Mobile App Development. Yes! You heard that right. He specializes in Mobile Apps using Titanium Appcelerator to build for Android & iOS but that didn't stop him from also learning Web stuff and Project Management using SCRUM, not to mention that he's proficient with Photoshop and some design tools but he's not much of a Designer at heart. What separates him from the rest is he don't have that "just build" mentality. He always does his very best by contributing to the team solutions that would make the quality of the project better. He considers User Experience as an integral part of his work which is a quality of a rare developer. Lately he's been involved with pure native Android Development and had spearheaded numerous projects at his young age. He's now looking into learning native iOS development using SWIFT.
