Our collaboration with Docplanner, the world’s leading healthcare platform (operating in 13 countries and serving over 100M users), began in 2020 with what seemed like a straightforward request: integrating the platform with the National Health Fund’s e-WUŚ system in Poland. Very quickly, the scope expanded. We were asked to design and develop modules enabling e-referrals, e-prescriptions, e-medical leave certificates, and insurance verification with NFZ. Over time, this grew into a permanent cooperation that includes continuous support and development of e-health services. To date, we have successfully delivered five nationwide integrations in Poland and expanded our role to similar projects abroad.
