Portrait of Carlton Osinde Makini

About me

I'm hands-on with SQL, Python, advanced Excel, Tableau, Power BI and Alteryx, and I like building the automated validation, reconciliation and quality checks that make numbers trustworthy.

Outside of work, I serve as Director of Technology for PMI's Southwestern Ontario Chapter, and I'm building an LLM-powered platform that reconciles contract terms against billed revenue.
