As a JavaScript developer, I have 8+ years of experience in React Native app development. My expertise is in RESTful API with django-rest and react js or react native (mobile apps) on frontend. But to be honest i don't have the shining badge as a web designer, but my standard is Twitter Bootstrap, you can bring your own design or designer, or i will find it for you. I pride myself on going the extra mile for my clients. But don’t take my word for it, please read my cliental feedback for an unbiased opinion.
