What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can contribute to impactful projects and continue to grow my technical skills.

I am a dedicated Senior iOS Developer with extensive experience in building high-quality mobile applications. Currently, I work at Sii Poland, where I have successfully developed and maintained key features for various applications, including payment processing and third-party integrations. My collaborative approach with designers and backend teams has allowed me to enhance user interfaces and deliver robust solutions.

Throughout my career, I have worked on significant projects such as the mObywatel app for the Polish government, where I implemented features that improved citizen engagement during the 2023 parliamentary elections. My technical expertise includes Swift, SwiftUI, and The Composable Architecture, and I pride myself on writing modular, well-tested code. I am passionate about leveraging technology to create impactful user experiences and continuously seek opportunities to grow and innovate in the mobile development space.
