Senior🎓
Top SchoolColin Graham is a Technical Lead with 10 years of experience building resilient backend systems and developer tooling, currently leading platform infrastructure at HubSpot from Ireland. He specializes in Java/Groovy ecosystems, test-first engineering and automation—having designed an in-memory test rig, an oversight system for hundreds of thousands of daily tests, and an intelligent leasing system to optimize expensive end-to-end test entities. Colin has strong experience in distributed messaging and data platforms (Kafka, RabbitMQ, HBase, Cassandra) and a track record of improving CI/CD and developer productivity across enterprises. Comfortable in both legacy JEE and modern microservice landscapes, he blends hands-on engineering with pragmatic process improvements (TDD/ATDD, Scrum/Kanban). An early adopter of tools like Docker and PiTest in production teams, he pairs deep technical breadth with a focus on measurable test and release efficiency.
