Senior🎓
Top SchoolHalldor Stefansson is a software engineer with 11 years of experience building backend, cloud-connected and embedded systems, blending a mechatronics background with hands-on distributed systems work. He has a track record of improving reliability and delivery—designing Go microservices, reducing CI times, resolving concurrency issues, and cutting API usage and manual workflows across multiple companies. Comfortable across Go, .NET, Kubernetes, Kafka and cloud pipelines, he’s delivered billing and ERP integrations, developer tooling, and automation that shaved hours or minutes off recurring tasks. A pragmatic mentor and scrum master, he routinely onboards and coaches teammates while leading small teams to timely releases. Unusually for a backend specialist, his mechatronics and self-driving car studies give him a hardware-aware perspective that informs robust system integration and IoT work.
