At Improve International, I delivered a production-ready data platform in under four months, enabling self-service reporting for 300+ employees across eight-plus sources. I architected BigQuery, dbt, Dagster, Python ingestion pipelines, and a 150+ model medallion architecture with 350+ automated data quality tests.
Previously, I improved Altice Portugal's nightly batch performance by 3–4 hours and raised 9am SLA adherence to approximately 100% through DataStage and Control-M optimisation. I've also automated 30+ cross-department Power BI and Tableau reports, built SQL and SSIS data foundations, and delivered Salesforce–Siebel CRM integration work.
