Summary
👤
Senior🎓
Top SchoolMark Cassidy is an AI-native consultant and seasoned engineering leader with three decades of experience helping organisations modernise delivery, restructure teams, and harness AI to change how software is built and staffed. He combines deep platform expertise—especially Sitecore and Optimizely/DXP migrations—with hands-on delivery, P&L accountability, and practice-building across European and global consultancies. Mark moves teams from “we tried ChatGPT” skepticism to practical AI-augmented engineering through codebase-level enablement, readiness assessments, and redesigned estimation and staffing models that reflect AI-driven productivity shifts. He has run his own consultancy, led large Sitecore practices at EPAM and product work inside Sitecore, and now offers pragmatic migration and delivery approaches that can slash legacy migration cost and time. Based in Kiel, Germany, he’s open to Director/VP roles as well as advisory and fractional engagements, bringing a rare blend of vendor-side product insight and long-term implementation experience. An understated but valuable trait: he repeatedly turns pre-sales and technical due diligence into durable delivery outcomes rather than slide decks.
