Sean Hayes is a Senior Software Engineer with over a decade of hands-on experience building and leading WordPress-focused web architectures for media, sports, and enterprise clients. He combines deep PHP and front-end skills (React, JavaScript, HTML/CSS) with development management experience—mentoring teams, defining QA and release processes, and liaising directly with stakeholders. His work includes migrating major news sites to WordPress VIP, integrating paywalls and third-party services, and building React-based tooling to streamline editorial workflows for large sports organizations like the NBA. As founder of a Chicago WordPress consultancy, he pairs entrepreneurial initiative with production-grade engineering, often tackling performance, scalability, and migration challenges. An active contributor to the WordPress project (notably around the 3.8/3.9 era), he maintains a pragmatic balance between extensible architecture and practical client needs. Based in Naperville, IL, Sean is known for translating complex editorial and business requirements into maintainable, testable systems that ship reliably.
