Summary

Senior🎓
Top SchoolHannes Rammer is a Senior Software Entwickler with 12+ years of hands-on experience building full-stack and IoT solutions across Ruby on Rails, Java and C#. He combines backend expertise (PostgreSQL, REST/GraphQL, RSpec) with DevOps-driven delivery (GitLab CI/CD) and a proven track record of automating business processes and improving workflows by ~20%. At Sensorberg he helped deliver cloud-linked door gateways and an alarm system for 4,000+ storage rooms, and at Bundesdruckerei he led helpdesk modernization and centralized contract automation. Comfortable stepping into leadership, he temporarily absorbed the workload of five engineers, served as interim IT head, and acted as tech lead coordinating external teams. Curious by nature, he pairs software work with DIY projects, 3D printing and VR/AR exploration—bringing practical maker instincts to engineering problems. Based in Berlin, he favors projects that intersect R&D, hardware integration and scalable, auditable systems.
