The X12 ↔ FHIR Field Checklist
The mapping questions to ask before you write the first line of converter code — from real implementations, not a whitepaper.
Healthcare Data Engineer

I build software that turns healthcare data standards into things that run — FHIR clients, validators, X12 ↔ FHIR converters. I focus on the parts that break in real implementations: schemas that drift, profiles that validate differently than you expect, and ETL jobs that stop at the edge cases. This site is where I collect what I learn along the way — working tools, honest write-ups, and the field checklist.
