Summary
🤩
RockstarDavid Murphy is a Senior Database Engineer and DBRE leader with 12+ years designing resilient, cloud-native data platforms and driving large-scale migrations across MySQL, PostgreSQL, MongoDB and Kafka. He has a track record of turning operational pain into repeatable platform services—leading a MySQL 8.0 upgrade in under six months, cutting DR prep from six person-months to under one, and migrating 60% of stacks to cloud/Kubernetes. David blends deep full-stack troubleshooting (networking, Linux, app and DB layers) with strategic cloud planning and access automation, having modernized access via Okta JIT and standardized TLS and IaC patterns. His experience spans startups to global enterprises—building SWAT teams, defining cyber standards, and presenting AI/cloud research at conferences during a Huawei tenure. Known for mentoring engineers and authoring ADRs/PRDs, he emphasizes measurable operational improvements and platform thinking rather than ad-hoc support. Based in Dublin, he pairs hands-on execution with a knack for reducing toil and scaling teams and systems.
