What I'm looking for

I seek BI/data roles where I can design ETL and data warehouses, build impactful dashboards, collaborate with cross-functional teams, and grow in data science and cloud deployment.

I am a Business Intelligence Developer with practical experience in SQL-based data modeling, ETL design, and dashboard development using Power BI and Tableau. I have built a PostgreSQL data warehouse and implemented ETL with Talend, improving load times by 40% and reporting speed and accuracy by up to 80%.

My work spans building KPI-driven visuals for microfinance and utility clients and co-developing a custom ECL calculation model within ±1% of IFRS9 guidance for a large SACCO. I collaborate closely with engineers and statisticians to deliver full BI solutions that significantly reduce report generation time.

I am pursuing an MSc in Data Science and hold foundational training in programming, machine learning, and cloud-based model deployment. I seek roles where I can apply robust analytics, ETL best practices, and clear data storytelling to drive measurable business impact.
