Education

  • BA
    Polish-Japanese Institute of Information Technology in Warsaw
    2019
    I directed a group of four individuals in the development of a medical app designed to track and calculate Warfarin dosage for patients with cardiological problems. The app provided a range of critical features, including medication reminders, dose calculations based on prior doses and blood results, and summaries sent to doctors for review. In case of an adverse reaction or other issue, doctors would receive a detailed notification, enabling them to take prompt action. As part of my role, I was responsible for creating iOS part of the whole app and distributing tasks among team members. We worked closely with a cardiologist who served as a subject matter expert, ensuring that the app's functionality is aligned with the needs of the medical community. Unfortunately, due to financial constraints, the app was not able to be maintained after we left the university, as no parties were willing to cover its ongoing costs.
