Top SchoolKeith Mcdonnell is a Senior Ruby on Rails engineer with nearly two decades building payment platforms, workforce systems and high-throughput backend services. He has architected PCI-compliant payment pipelines processing over 2.5M monthly transactions and recently shifted into AI integration, shipping production chatbots that handle thousands of daily conversations with enterprise-grade reliability. His work spans full-stack backend systems—Redis, PostgreSQL, Sidekiq, Kafka—and cloud platforms like GCP, with a consistent focus on automation, testing and operational resilience that reduced AI deployment failures to under 1%. As a founder he designed a CI-parallelisation GitHub App that cut a large test suite from five hours to three minutes, demonstrating a knack for practical performance engineering. UK-based and remote-first, he’s open to contract or permanent roles where secure, scalable systems and pragmatic AI adoption matter.
