Background

About Mark Hendrzak

I’m a technology executive who believes that enterprise systems shouldn’t just support the business — they should drive it forward. Over the past 20+ years, I’ve led large-scale digital transformations, data strategies, and integration initiatives for Fortune 50 companies, delivering high-performance solutions across HR, Finance, Supply Chain, and Data domains. I build strong engineering cultures, modernize complex ecosystems, and create real business value through scalable, secure platforms. Here are a few ways I’ve delivered impact: Led global HR system transformation from SAP/SuccessFactors to Workday for 85K employees and 38K contingent workers — streamlining operations and enabling $2B in annual payroll transactions. Reduced integrations by 40%(415 to 247) through a unified API-led strategy leveraging MuleSoft and Workday Extend. Built and retained a high-performing, 60-person global team with <5% turnover across onshore/offshore, FTEs, MSPs, and contractors. Delivered $100M+ in annual incentive program value via a custom full-stack Java platform. Developed 6 enterprise-grade Workday Extend apps — several featured at Workday conferences. Achieved 99.9% uptime across mission-critical HR and payroll applications while embedding DevOps and security-first practices. Prototyped AI/NLP solutions for attrition forecasting and sentiment analysis — modernizing HR intelligence and employee engagement. My experience spans enterprise architecture, ERP modernization, API management, integration strategy, Workday HCM, SAP, Oracle, MuleSoft, data governance, and DevSecOps — all at scale. I’m currently exploring senior technology leadership roles (Senior Director / VP level) where I can lead digital transformation, elevate engineering performance, and drive measurable business value. Let’s connect if your organization is building the next generation of enterprise platforms — and needs a proven leader to deliver it.
