Derek Mortimer is a London-based consultancy technical lead with 11 years of experience building resilient, cloud-native platform and SRE solutions across media, fintech and energy sectors. He combines hands-on engineering (Kubernetes, AWS/GCP, Terraform, observability stacks) with leadership coaching to help teams scale platform engineering practices and improve developer experience. Derek has delivered large-scale streaming and ingestion systems (Kafka/Akka at OVO) and re-architected monitoring and PaaS platforms to drive cost, reliability and deployment improvements at organisations like BuzzFeed and Thought Machine. He’s a vocal advocate for immutability, automation and strong team culture, and actively champions equality and diversity initiatives within the workplace. Unusually for a tech lead, he pairs deep academic grounding (PhD in Computer Science) with practical delivery, bringing protocol-level thinking to platform design and operational accountability. Outside work he’s known for a fondness for cakes and tabletop RPGs, a small hint at his collaborative, creative approach to problem-solving.
