The history behind the Kodjin Terminology Service

Building Ukraine’s nationwide e-health system was both fun and challenging. We had to handle various terminologies (e.g. ICPC-2, ICD-10) and integrate what were often complicated data sets into a coherent system.

Our team quickly realized that most solutions available in the market didn’t meet the project’s needs. Intricate logic and the sheer volume of data from the source systems created additional roadblocks.
