What I'm looking for

I'm looking for an application support role where I can investigate data and workflow issues, improve business-critical processes, collaborate across teams, and continue developing my systems, EDI, and analytics skills.

I support business-critical operations at Decora Blinds, Mzuri Group, resolving issues across Dynamics NAV, Blindata, Sysco, website administration, and EDI platforms. I run daily error checks, coordinate fixes with suppliers and teams, and help reduce failed imports and invoice disputes.

I investigate order, invoicing, dispatch, pricing, and EDI data discrepancies, applying practical data and configuration fixes while keeping users and developers informed through Jira. I've mapped and validated Blindata and NAV data for migration, documented workflows, tested fixes, and trained colleagues on release processes.

My earlier customer-facing roles at Holiday Inn and Carroll's Irish Gift Shop strengthened my calm communication, payment processing, operational data monitoring, and ability to resolve issues quickly. I enjoy connecting teams, systems, and data to keep work moving smoothly.
