About Me

Solution Architect in CSL’s IoT Engineering Solutions team. I architect, design, and develop eSIM orchestration systems — including our flagship eUICC product, rSIM.

Specialist in SGP.32 eSIM and active member of the eSIM work group, collaborating with industry experts to push GSMA standards forward. My work spans the full stack: from low-level modem integration and cellular protocol deep-dives to orchestration platforms and secure element architecture.

Previously led firmware development on RTOS-based alarm communicators, built autonomous HIL test harnesses, and served as Scrum Master. Always chasing the next hard problem.
