I build reliable Python and SQL data pipelines, warehouses, and validation frameworks for analytics.
United KingdomWhat I'm looking for
At SwapMoney, I build Python and SQL workflows that ingest, transform, and validate multi-source transactional data for analytics and downstream business use. I create fact and dimension structures, automated validation checks, and reliable Power BI reporting inputs.
I've also designed and reviewed ETL workflows across consulting projects, testing source-to-target mappings, transformation rules, edge cases, and acceptance criteria. I bring 5+ years of data engineering experience, an MSc in Data Science, and hands-on practice using Codex for implementation review, debugging, and technical analysis.
