Developed the HR Portal web app in React Native for Web from scratch as the only front-end developer in the project. I was developing a React Native library for components shared between web and mobile applications. I needed to display a lot of data on the HR Portal, including charts, diagrams, etc. I created many reusable components that could look different depending on the theme.

I integrated premium subscriptions into the existing mobile app. It included limited free access for new users. I also created in-app purchases integrated with Apple's App Store to enable payments. This new feature was hidden behind a feature flag in Firebase so we could easily turn it on and off in the live app.

An application for sharing photos from events such as weddings.

It provides a simple way to create photo albums that can be shared with friends. Uploaded photos can be further ordered as a physical photo book. I was responsible for the deployment and development of new features. In addition, I checked pull requests and wrote tests.

An application that allows you to remotely take care of someone’s grave, clean it or light a candle when it’s in a different city.

It is my own idea and I created the application from scratch.

An application that allows you to create family journals that can be shared with your grandparents. Journal is created in the application, and then photos are printed every month and sent to the elders.

I was the main mobile developer here. My role was to maintain and refactor existing code and develop new features. I also implemented an in-app chat using Channelize API.

An application used to rent electric vehicles. The application works in 11 different countries so it is focused on internalization. There are also a lot of interactions with the map.
I was in charge of maintaining the existing code and adding new features.

The application could scan beverage labels using the phone's camera and display some information in AR technology. The AR SDK was implemented in native technologies, and my role was to connect it with React Native by a Bridge. I worked in a team with other mobile developers.

Very extensive application which allows hotel customers to book and pay for the stays, order dishes in the hotel’s restaurant, and more.

I implemented an ability to create new themes of the app to be reusable by different hotels.

Two mobile applications that allow users to book beauty services. The first for clients and the second for service providers. These applications had a common codebase that was separated into a library.

I was the only mobile developer on this project and I created both applications from scratch.

A mobile application that is a kind of a social media service for nail artists and the company's clients. My role was to develop new features and maintain the existing code. I also deployed the application to stores.

A mobile application for pilgrims that follows their route on a map. I created this application from scratch. The biggest challenge was to display the GeoJSON data returned from the back end on the map.

A mobile application that facilitates communication between the agency and its clients. I was responsible for maintaining the existing code and writing new functions. This application contained a large number of forms and surveys, so I was responsible for their validation and for sending them to the back end.
