I managed multiple features and widgets, participated in structural refactoring, and supported the shared library utilized by the iOS team.

I was actively involved in preparing releases across multiple app stores and wrote comprehensive tests to ensure the longevity of application functionality.

Park Smarter

A cross-platform application for Android, iOS, and web, that I built for IPS Group to modernize their parking system and support modular expansion. I actively participated in technical discussions and architectural planning from project inception.

I developed key features, including camera-based license plate registration, user login, and the parking widget. Upon reaching MVP and completing testing, I was appointed to lead the development of a new instant app module and managed a team of three engineers. The project was executed in a Scrum environment utilizing MVI architecture and Clean principles.

Developed a native Android application for a network of EV charging terminals, ensuring strict adherence to German and Austrian regulatory compliance standards. I architected the complete application structure using Clean Architecture and Jetpack Compose, designing a modular UI/UX validation flow that guarantees a seamless payment and charging process for end-users.

I collaborated closely with the back-end team to integrate secure APIs and define data contracts, ensuring real-time synchronization with the charging infrastructure. Additionally, I took ownership of the QA process, identifying and resolving critical edge cases related to hardware-software communication prior to the successful market launch.
