👤
Senior🎓
Top SchoolJohn Halse is a seasoned software architect with over two decades of experience designing and implementing large-scale preservation, storage, and search systems, now shaping architecture at Skatteetaten. His background blends deep Java/J2EE expertise with XML, metadata modeling, federated identity and free-text search, honed during a long tenure as Senior Software Engineer at the National Library of Norway. He has hands-on open-source contributions to digital preservation tooling—fixing locale and internationalization issues in the widely used OpenWayback project—and earlier helped build Heritrix at the Internet Archive. Comfortable moving between low-level date/locale correctness and high-level archival workflows, he focuses on reliable, standards-driven solutions for huge data collections. Based in Nordland, Norway, he pairs academic training in informatics with a rare mix of institutional archives experience and practical backend development.
