    Android-iOS Leads

    India - Tests: 2

    We are a team of android and iOS leads. Most of us have, more than 5 years of experience in mobile doman itself. We have completed very complicated projects successfully. We are proficient in Multimedia apps, GPS tracking apps, Location - Maps Based apps, Complex DB & Network operations based reader apps, M-Commerce apps, and the list is long! We are also proficient in using github and project management tools (based on agile) like, asana, target on process, basecamp, mingle, etc OUR BELIEFS : ---------------------- We strongly believe in perfection that is the reason we consider even minor details because we know those small things in application will differentiate our apps from the crowded app market. We believe in handling all the exceptional cases gracefully in the application as stores are already over-loaded with crash full applications. We believe in pixel perfection and awesome UI designs, but keeping in mind the UX of the application, so that users may fall in love with our master piece!
