What I'm looking for

I’m looking for remote, asynchronous work in Central European Time, preferably part-time, where I can evaluate AI outputs against written guidelines and sources and apply my healthcare data and regulatory analysis experience.

At NXT HEALTH, I translate Polish public-funding regulations for primary care into data requirements, calculations, and test cases. I built a rule engine that reproduces selected NFZ funding calculations, with every figure traced back to its source act.

I also built an analytics cockpit using public NFZ contract and quality-indicator data, and designed a pre-visit clinical workflow tool that tracks authorship for every data point. The workflow marks missing data as missing rather than treating it as zero.

In 2026, I submitted written comments in NFZ public consultations. The NFZ confirmed that three of my five comments on the R_UMX 3.2 settlement message standard were incorporated into Ordinance 94/2026/DI.

Earlier, at Groupon, I designed and trained customer-service chatbot conversation flows and worked on business analysis of AI solutions. I also analysed requirements and business processes at ING Bank Śląski, and have written several hundred laboratory-result analyses through my own research practice, CZERNIHealth.
