There was an interesting challenge: create a cross-platform VR application for 5th anniversary of the company using Unity 3D. In 3 weeks! Of course I did it. Mainly now: lead iOS developer for existed e-commerce project from other supplier. Made a huge work of app stabilization: refactored with Clean architecture, added DI (Resolver), etc. Also inserted new technologies, such as Structured Concurrency. Began to add new features to application, also make suggestions of it's improvements touching POs with design and QA teams.

An "evening hobby" work for «keeping in shape» - help with 3 different projects. All of them using SwiftUI. A wide variance of interesting (but sometimes mind-blowing) tasks. But mostly - creating adorable screens. My personal win - decrease memory usage up to 8 times (50 Mb in peak instead of 406 Mb).

Kiyv, Ukraine

Develop an application for charging electro cars with a home station and in public from scratch. As a first developer on a project I chose and developed a foundation of architecture of this application (clean architecture + MVVM), developed complex UI components using Core Graphics and Core Animations. Also, I helped with setting up CI/CD processes, researched info about cards for wallets with NFC tags, made estimations for new features, and gave consultations to new members of the mobile team about requirements.The reason for leaving: I was invited to a project which is fully developed with interesting frameworks for me: SwiftUI and Combine.

Remote

Developing the application and the framework for the company. Exciting of different tasks, not only redesign some screens, «send POST/GET request and show the result», covered the code with unit tests. It’s about recording selfie video while tracking the face (if it’s gone, recording stops), made OAuth for Google and Apple in our own OAuth mechanism, recognizing the text of the passport MRZ and reading the biometrical data from it via NFC.

Finalization of the application: - adding interactions with new API methods (Alamofire); - review, code cleaning, elimination of memory leaks; - Adding new screens without a storyboard (using SnapKit); - Changing other parts of the application for a new design, adding animations; - interaction with Yandex API; The reason for leaving: the closure of the development of the mobile application.
