What I'm looking for

I’m looking to drive ethical, high-impact procurement that improves cost discipline and supplier performance. I want to lead end-to-end sourcing and inventory work, using digital tools and KPIs to deliver faster decisions and stronger project outcomes.

I’m a results-driven Procurement & Supply Chain Manager with 4+ years of progressive experience improving procurement outcomes across Kenya’s construction and public-sector environments. I focus on measurable cost reductions, stronger supplier performance, and operational excellence.

I manage the full procurement lifecycle—from strategic sourcing and competitive tendering to contract negotiation, import procurement, and regulatory compliance. I’ve renegotiated 12+ long-term supplier contracts, achieving an average 15% cost reduction without compromising quality or delivery timelines.

I also strengthen inventory and warehouse execution by building practical systems. I designed a warehouse inventory management framework that cut stock-outs by ~30% and eliminated excess inventory waste, and I streamlined the procure-to-pay (P2P) cycle to reduce average purchase order processing time by 20% through workflow improvements and digital tools.

In leadership, I’ve managed 50+ active supplier relationships and onboarded/performance-evaluated 15+ new suppliers, reducing single-supplier dependency. I ensure compliance with PPADA 2015, lead supplier evaluation scorecards that raised performance by 25%, and build KPI dashboards to support procurement decisions and continuous improvement.
