Maker of Invoicepak.

About

I’ve spent 10 years building WordPress, WooCommerce and Shopify stores, first as a junior software engineer at weDevs, now as a senior software engineer at SELISE Bangladesh Ltd, with freelance work for store owners on the side. Fixing the same store problems over and over taught me one thing: if it keeps breaking, build a tool for it. Invoicepak is my latest, a Shopify app that creates branded PDF invoices for every order automatically. Always curious about what other makers are building, and what store owners still do by hand.
