I'm primarily a PHP developer that specializes in customizing Wordpress and WooCommerce, recently I have started customizing Shopify themes as well. Most of my clients are independent web store owners who need help with customization and adding functionality to their websites:
I would like to be clear that I'm a programmer and not a web designer, if you need help with branding, colours and graphics then I'm not the right person for that job. I can however build out a theme based on a designers specifications.
