Summary

Senior🎓
Top SchoolLorcan Mcdonald is a Principal Platform Engineer with 17 years building cloud-native data and platform systems, currently leading platform efforts at Fanatics after directing engineering at Vectra AI. He specialises in automating developer workflows and production operations—turning slow batch processes into near real-time streaming and cutting ETL latency from hours to minutes while reducing costs. Lorcan combines hands-on language fluency (Haskell, JavaScript, Python) and strong Unix/DevOps instincts (Docker, Kubernetes, Terraform) with experience managing distributed teams and on-call rotations across geographies. He has repeatedly driven faster release cadences and resilient systems (zero PagerDuty alerts during Black Friday) and brings an engineer-first approach—if a computer can do it, it should—paired with a background in product-focused startups and security-conscious cloud migrations.
