Feb 2006 - May 2011 • 5 yrs 3 mos

Led the planning, development, deployment, and organization-wide implementation of the company’s ERP system, overseeing the complete lifecycle from requirements gathering and development through testing, user training, rollout, and post-deployment support. The ERP platform was successfully deployed across more than 200 distributors, 6 regional offices, 3 depots, and the company’s manufacturing facility, becoming a core operational system supporting sales, distribution, inventory, and business operations. During my tenure, the organization transitioned from a legacy Visual FoxPro-based ERP to a modernized solution developed using Visual Basic and ASP.NET. I worked closely with business stakeholders, development teams, and end users to ensure successful adoption, process alignment, and operational continuity across all locations.
