Hi, I'm Chiamaka

I'm a business analyst with a background in Supply Chain planning and Procurement. I've worked in Materials planning (MRP), inventory planning, deployment and replenishment at AB InBev and in procurement at Access Bank. I also hold a Master's (MRes) in Computing from the University of Bolton, where I built a machine-learning decision support framework for inventory replenishment planning.

I connect how a business works with what its data and systems need to do, turning operational problems into clear requirements, KPIs and data-backed decisions.

Based in: Greater Manchester, UK · Looking for: Business Analyst, Data Analyst, Supply Chain Analyst and Supply Chain Planning roles
