About

I’m a versatile technical professional with a hybrid background in business operations (Procurement/SAP) and software development (Java/Web Stack). I’ve consistently optimized workflows and bridged the gap between tech teams and business users, delivering practical solutions that align with real-world needs.

I can read code logs (Node.js/React) to troubleshoot errors, navigate ERP systems to fix data issues, and communicate solutions in clear English. I’m seeking a remote or hybrid role in Application Support, Implementation, or Technology Operations.
