What I'm looking for

I'm seeking opportunities in Business Intelligence, Data Analytics, or Junior Data Engineering where I can build reliable reporting, dashboards, ETL pipelines, and data solutions that support business decision-making.

At TIMWE, I develop SQL-based reports, validate and reconcile large datasets, and build SSRS reporting solutions in Visual Studio for operational and business stakeholders. I also create data segments and analytical outputs that support data-driven decisions.

I'm building on a Biomedical Engineering and Biophysics background through practical work in Power BI, SQL, ETL, data warehousing, Databricks, Google BigQuery, Oracle PL/SQL, Tableau, and PostgreSQL. My projects include KPI dashboards, Apache Superset monitoring dashboards, predictive machine-learning models, and healthcare-focused analytical work.
