What I'm looking for

I’m available immediately and prefer remote work within Mexico, or a negotiable hybrid arrangement from Puerto Vallarta, Jalisco.

At Neitek, I integrate the Pretoria project with SAP S/4HANA using services, stored procedures, and production and inventory notifications. I also adapt inventory and production flows using flat files and WSDL/SOAP services, and fix and promote catalog stored procedures across QA and production.

At Tafer Resorts, I designed and delivered hospitality solutions with REST APIs, SQL Server, IIS, and web modules. I supported the SAP S/4HANA migration and implementation, built ABAP services and modules, and integrated sales channels for availability, rates, and reservations.
