Hello. I'm a senior mobile developer with extensive experiences at building mobile(iOS/Android) apps with high quality for 4+ years. I have built Dating app, Chatting app, Social Networking app, Education app, Photo sharing app, Video sharing app, Geolocation app, Reservation/Ordering/Delivery app, Traveling app, Health/Fitness app, Utility app successfully. I usually build apps using Objective C/Swift and Java in native platform and am very familiar with various frameworks such as Google Maps, Quickblox, OpenCV, AVFoundation, Facebook, Twitter, Google+, Instagram, Stripe, Braintree etc. The most important thing for me is to build long term relationships with clients, so I am primarily looking for long term projects. I will work for 40+ hours per week and am happy to work closely with any freelancers who already worked with you. I will be very punctual, so will keep deadline and delivery good results. I'm looking forward to hearing from you. Best regards. Sebastian.
