I'm Yegappan Sekar — a Senior Web Engineer based in Coimbatore, India. I build ecommerce tools, automation systems, and data pipelines that run on thousands of stores worldwide.
At Cartrabbit, I lead web engineering across multiple products — Retainful (email marketing automation), Afflr (affiliate marketing), WPLoyalty (points & rewards), and UpsellWP (upsells & cross-sells). These tools collectively run on tens of thousands of WooCommerce and Shopify stores worldwide.
My work sits at the intersection of product engineering, automation, and data systems. I'm as comfortable writing a WordPress plugin hook as I am architecting a Google Apps Script pipeline that processes 17,000 URLs overnight. I believe software should solve real problems, run reliably at 3 AM, and be maintainable by the next person.
Outside of plugins, I build internal automation tools — Shopify app detectors, bulk email verifiers, Chrome extensions for web scraping, and comprehensive data dashboards that replace hours of manual work with a single trigger.
When I'm not at a keyboard, I'm exploring how automation is reshaping ecommerce, and occasionally writing about it here on the blog.
