Data & ML engineer building production-grade data pipelines and scalable ML systems.
United KingdomWhat I'm looking for
I am a Data & ML Engineer focused on building production-grade feature stores, high-performance data pipelines, and scalable neural network solutions that bridge engineering and data science. I specialize in automating data and model lifecycles, improving data quality, and reducing incident rates through validation suites and robust ETL design.
Across roles I have optimized ETL and BigQuery pipelines, engineered S3-to-Snowflake model-ready layers, and contributed to CI/CD for faster deployments. I deliver measurable impact—speeding reporting cycles, lowering incident tickets, and enabling validated datasets for fraud and predictive models.
