What I'm looking for

I'm looking to build reliable real-time, safety-critical, or cloud-native systems where I can work close to hardware and infrastructure, solve complex reliability problems, and continue growing through meaningful engineering ownership.

At Nokia, I led a full rewrite of the production Go debugging tool koredump, reducing resource usage and simplifying failure analysis for Kubernetes-based 5G systems. I also maintain Kubernetes controllers for coredumps and NIC firmware while helping transition network components to cloud-based infrastructure.

Previously, I developed ASIL-D steer-by-wire firmware at Bosch and ECG acquisition device firmware at CardioID Technologies, working across C, FreeRTOS, CAN, ESP32, and real-time constraints. I enjoy building dependable systems, from low-level hardware validation to fault-tolerant communication, and have also supported teams as a Scrum Master and Scout Leader.
