I am a developer with 8 years of commercial experience including 5 years of full-time freelancing. Now you can have Android app, iOS app and PHP/Python backend developed by a single person. No need to hire 3 separate developers. This way you can reduce your costs considerably and be sure that all components will work seamlessly together. I can also do simple graphics design and can work with .psd files. Additionally I have experience with HTML, CSS and JavaScript and various MVC frameworks. I have a lot of experience with Amazon Web Services and complex server infrastructure administration. I have team leading experience. My goal is always to bring your project to completion with a result the exceeds your expectation.
