I’m a BI Developer based in Durban, where I turn complex data into clear, decision-ready insights for teams across marketing, finance, and analytics. I work with SQL and modern data platforms like Snowflake, along with tools such as Tableau and dbt, to build reliable reporting foundations and “source of truth” dashboards. Beyond dashboard development, I enjoy making reporting workflows more efficient through automation—like scripting Tableau report downloads to reduce manual effort for stakeholders. I also bring a strong analytical background from data science training and certifications (including IBM Data Science), which helps me combine data rigor with practical BI outcomes.…I’m a BI Developer based in Durban, where I turn complex data into clear, decision-ready insights for teams across marketing, finance, and analytics.
