Summary
👤
Senior🎓
Top SchoolSebastian Rex is a Senior Software Engineer with 11 years of experience building mission-critical, cloud-native telecom and defence systems, most recently authoring microservices in Rust for Azure for Operators and deploying to AKS. He progressed from hands-on SIP interoperability testing and mobile support into technical leadership roles, shaping requirements, breaking down complex work and mentoring engineers across teams. His language breadth spans C++17, Rust and Python, with a history of developing IMS cores, session border controllers and online services at scale. Comfortable across the stack, he combines low-level systems thinking from telecoms with modern cloud-native patterns and CI/CD deployments. Based in the UK with a Natural Sciences degree from Cambridge, he brings a pragmatic engineering style that balances reliability, performance and team development. An uncommon strength is his ability to translate telecom protocol nuance into maintainable microservices architecture.
