Top SchoolAlex Ciminian is a Senior Software Engineer based in London with 15 years building large-scale, production-grade systems across observability, security, and infrastructure. He has led and bootstrapped teams and products—most recently founding Datadog’s Dynamic Instrumentation effort and driving its journey from inception to public beta—while alternating between hands-on backend work and engineering management. His technical breadth spans JVM/Java/Kotlin, Go, Kubernetes, TypeScript and cloud-native tooling, with notable contributions to Datadog’s Java APM and profiler (including profile uploads and container-identification improvements) and a track record of shipping services that run on hundreds of thousands of machines. Previously he helped secure and operate thousands of microservices at Monzo and scaled developer-facing observability tooling at Amazon, often improving performance and developer productivity by orders of magnitude.
