👤About
15+ years building production systems across every layer. PCB design and firmware at one end, enterprise Kubernetes platforms at the other. I've worked embedded systems, IoT hardware, mobile apps, backend services, DevOps, and cloud architecture professionally, not as side projects.
I ramp up fast in new domains. Game dev infrastructure: built a complete Unity CI/CD platform with zero-idle-cost AWS runners. Automotive security: delivered PCI compliance and CVE management for Volvo's global platform across 1000+ nodes. Consumer hardware: shipped 1000+ IoT devices from circuit design through CE certification to market.
I work two ways. Fixed-price delivery where I own the full build and hand over a working system. Or embedded in your team as a senior engineer or architect, filling gaps your team doesn't cover. Either way, I make the technical decisions and I execute on them.
Running WigertzTech AB since 2023. Based in Leksand, Sweden. Remote or hybrid, contract or team augmentation.
