Summary
👤
Senior🎓
Top SchoolKristian Rastrup is a senior consultant and seasoned software developer with 11 years of professional experience building integration-heavy systems using BizTalk, C#, SQL Server and SSIS. He has led high-stakes migrations and performance-critical data projects—most notably a time-bound, multi-system migration for ATP and a BizTalk platform overhaul at NNIT—demonstrating practical expertise in enterprise architecture and test automation. Comfortable across backend and integration stacks, he also has low-level systems experience from earlier C/C++ and Oracle work at Post Danmark. An active maintainer-style contributor, he’s applied his attention to detail to cryptography code in the BouncyCastle.NET mirror, fixing algorithmic and type-level issues. Based in Copenhagen, he pairs a cand.it. in software development from IT University of Copenhagen with a pragmatic, system-focused engineering approach. Colleagues rely on him for robust, production-ready solutions where correctness and performance matter.
