Data Reliability Engineer based in York, UK. I work on the infrastructure that keeps data trustworthy at scale — anomaly detection on large streaming datasets, LLM evaluation and testing pipelines, semantic and metadata layer integrations, and product analytics systems.
Most of my work lives in Python and SQL, with occasional excursions into Rust when performance matters. I hold an MSc in Data Science, where I researched probabilistic attention mechanisms for financial time-series forecasting.
