What I'm looking for

I’m looking for a BI/analytics role where I can build Power BI dashboards and automated data pipelines, support financial reporting, and collaborate with stakeholders to deliver reliable, decision-ready insights.

I’m a Data & BI Analyst with a BSc in Computer Science and Microsoft PL-300 certification, focused on Power BI reporting, SQL/Python analysis, and automated data pipelines. I thrive turning messy, multi-source inputs into clean models that make financial performance easy to understand and act on.

In my current volunteer role with a US-based non-profit, I automated three data pipelines across Zeffy, Relay Bank, and Interactive Brokers, removing manual data entry and improving reliability. I also built a secure Google Sheets-based data warehouse with role-based access and delivered monthly expense and executive reporting that combines banking and investment data.

I’m also the founder and BI consultant behind Zinaka Analytics in Zimbabwe, where I build and maintain a financial ledger Progressive Web App for SMEs. I deliver Power BI dashboard development, data cleaning, and analytics consulting—backed by client onboarding workflows that generate structured data before dashboards are delivered.
