What I'm looking for

I'm looking to build end-to-end machine learning and AI applications, including real-time inference APIs, automated pipelines, model monitoring, and data-driven analytics.

I've built production-style fraud detection systems using ZenML, MLflow, FastAPI, Redis, Evidently, and Prometheus, including automated retraining, data-drift monitoring, shadow deployments, and sub-200ms inference.

At Carbin Africa, I built Power BI dashboards and automated KPI reporting with Excel, Python, Pandas, and SQL, contributing to a 36% improvement in operational efficiency. I also developed a GraphSAGE fraud detection system that achieved 0.999 ROC-AUC and 0.936 AU-PRC.
