I taught myself to code in 1994 when I was 11 and have been working professionally building things for the web pretty much since then.
I've worked with too-many-to-count programming languages and technologies and have decades of experience with ecommerce, but my current interests are in serverless and machine learning.
Currently, I'm working to build the best free ecommerce platform in the world: https://www.stam.pr - Head over there to create a free online store.
Oh... and I wrote a book: http://www.sevendaystartup.com/
