Professional full-stack developer

I am a software engineer with 5 years of professional experience in building web and mobile applications for iOS and Android. I am skilled in all aspects of the full software development cycle, from requirements gathering and planning through development, release, and maintenance. In other words, I can do everything you need to build your app from the ground up and get it on the market which means I can turn your conceptual idea to real working software. Whether you are starting with a rough concept or already have extensive specifications and wireframes, I will work with you to turn your idea into a reality. Looking for someone to do maintenance or upgrades on your existing project? I can learn your codebase quickly, fix bugs, refactor messy code, and add new features as needed.
