More than a CV

A clearer personal narrative around research, systems, and technical depth.

The about page now leans into story, trajectory, and identity rather than looking like a plain resume export.

PhD researcher at University College Dublin

I work best where systems behaviour, measurement, and explanation intersect.
Professional summary

I work best where systems behaviour, measurement, and explanation intersect.

My background sits at the intersection of low-level performance analysis, distributed systems, and operational thinking. What ties the work together is a preference for evidence: profile first, measure carefully, explain the behaviour, and then decide what to optimise.

My story

A career built across energy systems, distributed infrastructure, and machine-level performance.

Period

2022 - Present

University College Dublin

PhD Researcher in systems performance and power analysis

Designing and validating models for multicore behaviour under Linux, combining low-level counters, instrumentation, and performance reasoning to explain how machines behave under load.

Period

2019 - 2025

Research and development project

Distributed systems engineer focused on Cassandra experiments

Built middleware, observability pipelines, and controlled environments to study consistency, stale reads, and energy-performance trade-offs in Apache Cassandra clusters.

Period
