HRIS & Enterprise Integration  ·  Solution Architecture  ·  Process Automation

Professional Profile

Integration architect with 18 years across enterprise systems, SaaS, and HR technology, specializing in the critical data flows HR and payroll run on: employee demographic feeds, recurring payroll elections, time and PTO reporting, and the reconciliation controls that keep payroll correct. Partnering daily with HR operations, payroll, finance, IT, and functional teams at organizations up to 100,000+ employees across major HCM platforms. Known as the technical escalation point for complex integrations that nobody else can untangle, and for leaving behind the documentation, tooling, and operational processes that let internal teams run them reliably long after go-live.

Experience & Impact

Solution Architecture

2023 – Present
  • Design and implement HRIS/HCM and enterprise SaaS integrations across major platforms (including Workday, SuccessFactors, Oracle, SAP, Dayforce, and UKG) via Boomi middleware, REST APIs, and flat files (XML/CSV, delta/PECI patterns).
  • Architect secure data flows covering employee demographic feeds, recurring payroll elections, time/PTO reporting, and enterprise file transfer automation for organizations up to 30,000+ employees.
  • Serve as the technical escalation point for high-risk, non-standard integration scenarios, leading root-cause analysis and designing durable workarounds, operational controls, and support procedures that protect ongoing payroll and business operations.
  • Build custom validation scripts, data-transformation utilities, business rules, and workflow tooling; author technical documentation and knowledge-transfer materials that keep systems supportable for internal teams long after go-live.

Lead Technology Consultant

2015 – 2023
  • Led SaaS workforce-management implementations and enterprise integrations (handling employee demographic data, payroll-adjacent feeds, and time/scheduling data) using Boomi, SQL, C#, and .NET.
  • Developed HL7 data-exchange solutions (ADT, orders, results) integrating clinical electronic medical record (EMR) systems into nursing workload management.
  • Played a critical role in enterprise ransomware incident recovery: rebuilt application environments from scratch across multiple product lines under strict data safety procedures, owning verification and return-to-service operations.
  • Created technical documentation and training materials that reduced support escalations; mentored new technical consultants through onboarding.

Director of Operations & Systems Administrator

2008 – 2017
  • Led cloud migration and infrastructure modernization from on-premises to a hybrid VMware–AWS environment with auto-scaling; introduced automation and monitoring that enhanced incident response and resilience.
  • Managed high-traffic public traffic and infrastructure platforms for government clients, driving capacity planning, high availability, and rapid troubleshooting while leading a team of systems administrators.
  • Rebuilt internal documentation and operational workflows following organizational transitions, aligning IT operations with development and product needs.

Success Stories

Enterprise Logistics Leader: Payroll Reconciliation at 100,000+ Scale

Protected payroll data integrity for a 100,000+ employee organization when a defective integration threatened to silently drop payroll records. Designed automated reconciliation tooling cross-checking API data, custom reports, raw source files, and output to surface clean exceptions and rebuild missing records via simple GUIs for non-technical payroll teams.

Major Medical Center: EMR-to-Workforce Integration

Resolved edge-case source data challenges for a nationwide healthcare provider integrating patient orders into nursing workload software. Built an intermediary C# normalization layer to handle edge cases and maintain launch timelines for daily hospital scheduling and patient care operations.

Enterprise Cybersecurity & Incident Recovery

Owned verification and return-to-service operations during a major cloud ransomware recovery effort, rebuilding application environments from scratch across product areas under strict data safety protocols.

Global Professional Services Firm: 48-Hour Data Consolidation

Rescued a stalled enterprise workforce-planning implementation by consolidating disparate source files within 48 hours using Excel, SQL, and Python, delivering a clean dataset that unblocked go-live and restored stakeholder trust.
