Senior🎓
Top SchoolBjörn Wilmsmann is a founder and independent IT consultant with 14+ years building enterprise web apps, SaaS products, and developer-focused courses. He combines hands-on Spring Boot and AWS expertise with front-end skills (Angular) to design, implement and operate production-ready systems, and automates deployments with GitHub Actions and the AWS CDK. As co-author and instructor for "From Zero to Production with Spring Boot and AWS," he translates complex cloud and DevOps topics into practical guidance while running client engagements across major Rhine-Ruhr and European cities. His background in computational linguistics and long track record of founding and leading tech ventures brings a rare mix of product sense, teaching ability, and infrastructure-first engineering. Notably, his open-source work emphasizes reproducible production patterns—Cognito, CloudFormation/CDK and OAuth2 flows—for reliably shipping Java-based services to AWS.
