Karen Borrero

Backend & eCommerce Developer

I'm a backend developer with over 10 years in technology. I specialize in Magento 2 ecommerce, SAP integrations, API development and AI solutions. I've worked on medium and large-scale projects — from loyalty systems active in 230+ stores to DTC integrations with SAP for the European market and MCP connectors for LLMs.

My edge isn't just technical: I come from support, project management, and running my own company. I understand how a business works before writing a single line of code.

Most of my work lives in private repositories — enterprise projects under NDA for companies like HiperDino (Dinosol), Hiberus, and Squaads. What you see here is a small sample of personal and open-source work.
