Senior🎓
Top SchoolTim Mickelson is a Senior Software Consultant based in Sweden with a broad 20+ year engineering background and six years of consulting experience delivering cloud-native and legacy-modernization projects. He blends deep systems-level experience (C/C++, Unix, Asterisk, telecommunications protocols) with modern Java, Kotlin and cloud toolchains (Azure, AWS, Kubernetes, Terraform, CI/CD). Tim has repeatedly driven monolith-to-modular transformations and production-grade DevOps practices for clients like Gunnebo and Skånetrafiken, and has architected scalable microservices integrated with OpenTripPlanner and GraphDB. He is comfortable across the full stack—from OAuth-secured Spring Boot services to serverless Lambdas—and brings a pragmatic focus on reliability, testing (Pact, Testcontainers) and automated delivery. An owner-operator at heart, he has also led teams and taught technical courses, pairing hands-on coding with long-term architectural stewardship.
