Data analytics developer at Freelance Data Projects, applying RAG and vector search with Databricks.

At Freelance Data Projects, I work with AI and LLMs, including RAG and vector search, alongside Python, PySpark, and Databricks.

At First Help Financial, I automated financial reporting for P&L, Balance Sheet, Trust, and Loan Tape, saving multiple team members two weeks per month. I also automated daily and monthly static files for external partners.

At Recargapay Ltda, I rebuilt Qlik Sense dashboards for internal reporting and Investor Relations. The work included migrating reporting data from AWS Redshift to Databricks and consolidating inconsistent tables into centralised ETL, dimensions, and measures.

At Geneva Ireland Financial Trading Ltd. and Allied Irish Bank PLC, I developed data pipelines and BI dashboards for trading, finance, and credit risk reporting. Earlier, at Greyhound Recycling and Recovery Ltd, I created automated management reporting and dashboards across business operations.
