5+ years | SQL · Power BI · Python · Automation
I'm Oluwadamilola (Damilola) Oyetayo, a data and business analyst with over five years' experience in logistics, facility management and the public sector.
I started with SQL, first teaching it and then building data models and reports. Today I lead workflow digitisation for a federal government agency, and in my own time I build automation and AI-powered tools.
What keeps me going is finding the insights hidden in data, and presenting them so that non-technical teams can act on them.
