What I'm looking for

I’m looking to build production mobile apps—own features end to end, deliver stable Kotlin/Compose and cross-platform experiences, and collaborate closely with designers, backend, and QA teams.

I’m a Mobile Software Engineer based in Poland, currently building and maintaining Android applications using Kotlin and Jetpack Compose. I focus on reliability, performance, and scalable architecture through MVVM and Clean Architecture.

In my recent role, I integrated REST APIs with Retrofit and OkHttp (including authentication flows and robust network error handling) and worked with Firebase services such as Firestore, Realtime Database, FCM, Analytics, and Remote Config. I also implemented configuration-based feature management and supported controlled feature rollouts.

Previously, I developed native Android apps at Mira Apps—building reusable UI components, navigation flows, and reactive interfaces with Coroutines and Flow. I integrated Firebase Authentication, local persistence with Room and DataStore, and improved application responsiveness and usability.

I also build cross-platform features using React Native and TypeScript, using patterns like Redux Toolkit and API integration with Axios. Alongside work, I develop self-initiated Android projects (AIVis, Weather App, and real-time chat) and publish source code on GitHub while continuously learning through experimentation and interview-style practice.
