Summary
👤
SeniorTomas Nilsson is a senior software engineer and system architect based in Malmö with over 20 years in the software industry and deep expertise in cloud-native microservices, security-by-design, and DevOps practices. He has led engineering and IT operations teams up to CIO level while remaining hands-on—designing API gateways, mTLS mesh networks, and high-security infrastructure using .NET, C#, Kubernetes, Istio, and Azure platform services. Tomas excels at modernizing legacy stacks and automating delivery pipelines, having migrated projects across .NET versions, introduced GitOps with ArgoCD, and formalized coding standards and linting across teams. He combines backend and fullstack experience (Next.js, Node, SignalR, RabbitMQ) with a pragmatic focus on code quality, security reviews, and developer enablement through training and process improvements. Notably, he frequently operates as a senior consultant in large-scale, regulated environments, bridging architectural vision and day-to-day implementation. Colleagues rely on him for practical, security-focused architectures that scale and for mentoring teams to adopt repeatable, automated delivery patterns.
