Senior🎓
Top SchoolNeils Schoenfelder is an Associate Software Developer with 12 years of experience building healthcare interfaces and integration solutions, currently consulting at Moxe Health on Mirth, C#, and HL7v2 projects. With a strong mathematics background (Master's-level, ABD) and broad language fluency from MUMPS to Python and C++, he quickly grasps and improves algorithms rather than just applying recipes. He has deep domain expertise from Epic and hospital integrations—designing complex bi-directional workflows that reduced duplicate messages and enabled lab and supply-chain automation. An open-source developer, he implemented a self-hosted ANSI-95 MUMPS parser and extended graph algorithms (a modified Tarjan) to detect left-recursion, revealing both practical and theoretical strengths. Based in Madison, WI, he’s drawn to hard problems and moonshot efforts like blockchain ledgers and graph databases that push traditional interface work into exploratory systems.
