PROFILE
Marc Hadley
Over three months, Michael Hadley enhanced the nightingaleproject/vital-records-dotnet repository by developing features that improved healthcare data interoperability, reliability, and compliance. He implemented FHIR condition resource alignment with US Core IG, introduced round-trip conversion between FHIR STU2 and STU3, and stabilized birth record processing through robust date handling and timezone consistency. Using C# and .NET, Michael refactored IJE field handling for accurate data formatting, expanded automated unit testing with xUnit, and enabled dual storage of occupation and industry codes across multiple standards. His work addressed cross-version compatibility, reduced data truncation risks, and established a maintainable, test-driven codebase.
