What I'm looking for

I’m looking for a role where I can build reliable ETL pipelines, validate migrated warehouse data, and deliver dashboards that teams can use for day-to-day decision-making.

At TSTT, I designed and implemented automated ETL pipelines in Python to ingest financial data from SFTP into data warehouses, with data integrity validation and SQL-based analytics support. I also built interactive dashboards in Tableau and Power BI and set up automated monitoring and alerting so teams could track cross-departmental decisions.

During a data warehouse migration, I created SQL verification scripts, ran UAT-style validation, and authored end-to-end migration documentation, including table inventories, dependency/lineage maps, and object classification matrices. I also conducted checks on Talend to confirm ETL processes had completed.

Before that, I supported data work as a Research Intern at StarApple AI—cleaning and preprocessing large datasets, doing EDA, and producing data visualisations and reports. At the University of the West Indies Mona, I graded and guided lab assignments, wrote scalable Python/Java/SQL code, maintained lab software, and helped teach teachers how to use AI tools like Chat GPT.
