Production Engineer focused on datacenter operations and fleet
management at scale. Eight years across Meta, Zalando, and Proofpoint
building workflow engines, deployment tooling, and observability
systems. Equally at home designing distributed backends and the
operator-facing UIs that sit on top of them.
Experience
Dublin, Ireland
-
Designed and built a workflow engine from the ground up to
orchestrate rack turn-up, coordinating multi-step provisioning of
new hardware from initial receipt through validation to serving
production traffic; used by on-site datacenter teams across
multiple regions
-
Built tooling covering the full rack lifecycle: receipt, turn-up,
in-place moves for power and redundancy optimisation, and
decommissioning
-
Developed logistics and planning tooling for rack operations
("rack touches"), enabling forward-looking staffing and execution
scheduling for on-site teams
-
Designed and implemented integrations reconciling vendor-supplied
hardware data with internal source-of-truth metadata, resolving
long-standing divergences across procurement, deployment, and
operational systems
-
Defined processes for new hardware introduction and on-site
execution, partnering with field teams across regions to reduce
coordination overhead and improve consistency
-
Instrumented the workflow stack end-to-end with metrics,
structured logs, and tracing to surface stuck workflows,
vendor-data drift, and execution bottlenecks early
