I can help your business by developing a responsive website/web app, or a phone app that works on both iOS and Android.
I started programming in 2011, and I got into web development in late 2015, since then, I've been programming almost everyday. I've studied web development on Coursera (you can find the verified certificates in my resume), Udemy, and FreeCodeCamp.
