Rockstar🎓
Top SchoolKasper Svendsen is a Senior Software Engineer with 11 years of experience combining deep academic foundations in theoretical computer science and a PhD in software verification with hands-on engineering of highly available distributed systems. He builds and verifies concurrent and distributed systems end-to-end, having led production migrations to active/active Cassandra, designed payment and deployment APIs at MobilePay and contributed to Uber’s cluster federation and cloud platform. Currently he works on the CodeQL compiler at GitHub, improving the language spec and documentation for a widely used code-scanning product that powers security research and enterprise scanning. His background in formal reasoning and memory-model research informs pragmatic system design and domain modelling, making correctness a first-class concern in production code. Colleagues rely on him for translating subtle concurrency properties into verifiable, maintainable implementations that scale.
