Summary
👤
Senior🎓
Top SchoolErik Siegel is a seasoned content engineer and technical writer with over two decades of hands-on IT experience and 12 years focused specifically on content engineering and XML technologies. As founder of Xatapult, he helps organizations bridge gaps in XML processing, content workflows and technical documentation, often taking roles from strategic consultancy to application development. He has practical experience modernizing legacy systems (e.g., migrating Ant-based pipelines to XProc 3) and has co-edited the XProc 3.0 specification and authored two books on XML technologies. Clients have relied on him to design custom content models (like ICoM combining DITA and QTI), build eXist-based solutions, and train both technical and non-technical staff. Based in Zwolle, Netherlands, Erik blends deep technical architecture skills with clear explanatory writing—a combination that makes his recommendations immediately actionable. An often-overlooked strength is his long track record of converting complex publishing and healthcare XML workflows into maintainable, standards-driven pipelines.
