Summary
👤
Senior🎓
Top SchoolJames Harrison is a Senior Data Engineer with 9 years' experience applying high-performance computing and software engineering to real-world humanitarian problems, currently leading data engineering at the Flowminder Foundation in Dublin. He designs and optimises pipelines that process terabyte-scale, sensitive geospatial mobility data on modest hardware, enabling crisis response, vaccination planning and national statistics across low- and middle-income countries. His PhD in computational particle physics underpins a rigorous approach to algorithm optimisation, parallelisation, and reproducible data modelling, which he pairs with practical skills in Airflow, Python, PostgreSQL and Parquet storage. He has a track record of reducing storage footprints and speeding crisis analyses from weeks to days, while training partners to adopt robust, privacy-conscious methods. Comfortable juggling varied roles in resource-constrained environments, he mentors teams, improves UX for analysts, and contributes to open-source FlowKit used for mobility analysis. Outside work he channels his curiosity into music, cooking and travel, reflecting a collaborative and inquisitive mindset that drives impactful technical solutions.
