9 years building enterprise applications and system integrations

From business analysis to deployment — software built around how operations actually run.

An IT professional with 9 years of experience, focused on enterprise application development and ERP integration. I start by surveying and understanding the business process, then digitise its data.

I have built real-time cargo delivery and yard-management features, developed VBA tools for production, integrated DoT stations that feed clean data into SAP, and currently mentor team members in application development.
