Profile

Leadership & Vision

Nelson Ochieng Were — Systems Engineer and Executive director in Nairobi, Kenya

I build the operational infrastructure African companies run on — not demos, not side projects. As Executive director of OptioHire and Director at Cres Dynamics Ltd, I lead teams shipping ERP, finance platforms, AI automation, and payment systems that process real revenue for real organisations.

Information Technology graduate, Jaramogi Oginga Odinga University of Science and Technology (2025). My track record was built in parallel with my degree: production deployments that paid salaries, managed teams, and solved operational problems at scale.

Every platform I have delivered is live today. My work sits where engineering precision meets executive clarity — systems that change how a business tracks revenue, manages teams, serves clients, and scales without the Executive director in every decision.

Before architecture or code, I map the business: decision flows, capital movement, friction points, and three-year trajectory. That discipline — business first, technology second — is the Cres Core methodology.
