About

Support engineering with enterprise depth and a systems mindset.

My work sits at the intersection of technical troubleshooting, operational clarity, and customer trust. I focus on turning ambiguous incidents into evidence-backed diagnosis, faster resolution paths, and durable improvements.

Professional Summary

At Unily, I support Fortune 100 clients through complex production issues, incident coordination, and full-stack debugging. Across previous roles at Direct Commerce, Jotform, and Ritam Technologies, I built range across APIs, front-end troubleshooting, automation, SQL, reporting, and release support.
