David Ansari is a Principal Software Engineer based in Hamburg with 11 years of experience building and operating large-scale distributed systems, notably driving core RabbitMQ features such as AMQP 1.0, MQTT 5.0, quorum queues and performance improvements that enabled millions of IoT connections. He combines backend systems engineering, cloud/platform work and DevOps — from implementing efficient Erlang/Elixir Raft internals and test automation contributions to gomega, to authoring Terraform and BOSH automation for multi-cloud deployments. At Broadcom (formerly VMware/Pivotal) he shipped production-grade observability, alerting and a Kubernetes operator for RabbitMQ, and has hands-on experience integrating secrets management with HashiCorp Vault. David’s work shows a pragmatic focus on reducing CPU/memory overheads (term_to_iovec, pread/pwrite optimizations) and improving reliability at scale, reflecting both deep systems thinking and attention to developer experience. He holds an MSc in Networked Computer Systems from UCL and a background in Cloud Foundry and OpenStack operations, bringing a rare blend of protocol design, performance tuning and infrastructure automation.
