(Telmo Amaro) was a pleasure to work with. This was my first experience into the world of app development and he explained everything well and was patient answering all my questions. (Telmo Amaro) kept me informed with very regular updates, including the reason for a short delay. All four products met my expectations and there is excellent after-sales service also. I wholeheartedly recommend (Telmo Amaro) and his work.
