The second application is also related to healthcare, but it's designed for doctors. Doctors can access their patients' test results and information through the application. Additionally, the application can receive data from healthcare devices such as scales, activity trackers, smartwatches, and temperature devices via Bluetooth. Once the data is received, I display all the information on the mobile app, including step counts, heart rate, patient weight, and more.
Another application is developed for a well-known publishing house in Norway. They have a website where they sell ebooks and audiobooks. After you purchase a book from the website, it becomes available on the mobile application. Using the mobile application, customers can listen to audiobooks or read them in PDF format.
Another app is designed for women, and its name is Symptom Mood Tracker. It doesn't have many features, as it was developed from scratch. I did implement some additional features for premium members. Customers can purchase these features using the in-app purchase option.

From a technical standpoint, I can highlight my work on developing extensions for open-source software used in cryptocurrency ATMs located in the United States. Due to logistical constraints, a client couldn't send one such ATM to Ukraine for testing. Consequently, my team and I collaborated with DevOps remotely to install firmware updates on the ATMs. We monitored the entire process and its results via a client's webcam in their warehouse. It was an incredibly satisfying experience to witness the ATMs functioning seamlessly after these remote manipulations.
I'm only considering Wise as a payment method, or using a payment provider.
