I build and optimize databases that hold up under real production load and turn raw data into reporting that actually answers business questions. Over 6+ years I've worked as a database developer and engineer across gambling, healthcare, and banking. Most notably, I spent 6 years with Flutter (the group behind FanDuel, Paddy Power, and Betfair), where I designed and built Oracle/PostgreSQL database objects from scratch - packages, procedures, functions, triggers - for revenue-critical promotional systems, achieving 4x performance gains through indexing, partitioning, and query rewrites, and later built ETL pipelines (Apache NiFi, ClickHouse, BigQuery) feeding BI reporting.
