Hi, I'm Chiamaka

I'm a Data 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 turn operational data into clear analysis, KPIs and dashboards that support better decisions, using SQL, Power BI, Excel and Python.

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

Projects

Supplier & inventory dashboard · live demo Stakeholder questions turned into a KPI dictionary, star schema, SQL, DAX and a working dashboard that links supplier OTIF to stockouts
ML demand shock prediction My MRes dissertation: Random Forest vs. XGBoost vs. LightGBM predicting demand shocks, driving an adaptive replenishment policy that cut stockouts by 18.5%
Sustainable supplier selection Explainable ML for procurement: a Random Forest that classifies suppliers on sustainability (89.7% accuracy) and shows which factors drive the decision
SQL: Data analyst job market PostgreSQL analysis of 2023 job postings, with my own comparison of UK data vs. business analyst skills
Inventory deployment planner Business rules for deploying stock to depots, built into a rule-based Excel planner with BPMN maps and automated checks
