Zurich, Zurich, Switzerland
Summary
👤
Senior🎓
Top SchoolOliver Gramberg is a Senior Consultant in testing with over 20 years of software engineering and research experience, currently based in Zurich and focusing on security-sensitive systems and test process improvement. He has repeatedly discovered critical security and data-handling bugs across banking, insurance, telecom, identity verification and healthcare domains, and has hands-on experience rewriting modules to improve correctness and maintainability. Pragmatic about languages, he selects whichever general-purpose language best matches the problem—Perl for text, R for statistics, C# for rich UIs and even Prolog for logic puzzles—reflecting a deep interest in programming language theory and reducing cognitive friction. At Xebia and previously ERNI he blends test automation, CI/CD, UX critique and coaching to raise delivery quality, and he brings a rare combination of academic rigour from KIT and long corporate research experience to practical testing challenges.
