Shipping products that businesses run on every day
I'm Kajal, a Full Stack Software Engineer with5 yearsof experience owning production products used by 40K+ stores and 600K+ end users.
At WPXPO, I lead the frontend architecture across 9 WooCommerce products. That means refactoring legacy code into a component-based structure and keeping every product maintainer on one standardized frontend workflow.
I build and ship end-to-end features with Next.js, React.js and Gutenberg. My work runs in products like PostX, WowShipping and WowRecommendation, used by 40K+ stores.
I've also built 33+ business websites, 5 WordPress plugins and 15 Chrome extensions, and I maintain the Vue.js Bangla documentation.
The case studies below walk through the engineering decisions behind that work.
Case Studies

WowShipping Frontend Engineering - 4 Case Studies
4 case studies from the WowShipping WooCommerce shipping plugin's frontend: a Gutenberg component migration that didn't survive a branch merge, a hand-built drag-and-drop interaction, a naming-convention overhaul, and a domain-vocabulary rename.
