Workday-focused Senior Software Engineer at Integrity Marketing Group supporting enterprise HR and Finance integrations, reporting, and production operations.

Message

At Integrity Marketing Group, I support an enterprise Workday platform serving HR and Finance processes. My work spans employee lifecycle workflows, integrations, reporting, data quality, testing, and production support.

I design and support Workday Studio, EIB, Core Connector, RaaS, and REST/SOAP integration patterns. I also develop XML/XSLT and JSON transformations, mappings, validation rules, and reconciliation controls for enterprise data exchanges.

At Optum, I supported Workday HCM and employee lifecycle processes, including Recruiting, Talent, Compensation, and Payroll-related data. I maintained integrations and reports, validated data, and participated in testing and production incident investigation.

Earlier, at Marqeta and Livongo Health, I worked on enterprise integrations, APIs, reporting, and data conversion. I supported testing and production operations, using source-to-target validation and reconciliation to investigate data and interface issues.
