Projects & Employments

Current & previous projects

App Developer at Landskrona Stad, Helsingborg

Eager to leverage the advantages of open source, Landskrona City set out to implement a municipality-level reporting app similar to the one used by Helsingborg City. The app allows residents to report issues or submit requests directly to the municipality. The project began by forking Helsingborg’s existing codebase, allowing Oskar the the rest of the team to build upon and adapt it to fit Landskrona’s needs — including implementing the city’s own design, branding, and unique features.

Technologies: iOS, Android, Expo, Open Source Development

App Developer at ASSA ABLOY Entrance Systems, Helsingborg

Together with a colleague, Oskar developed an Augmented Reality (AR)–based door measurement app for ASSA ABLOY. The app’s primary function is to use LiDAR and AR technology to measure and simulate door placement in real environments — for example, visualizing how a door would fit in a garage. Users can also mark obstacles in the AR view that might hinder installation, ensuring accurate placement and measurements. Once the configuration is complete, the door setup is sent to an external virtual environment, where users can explore the door in greater detail. The app was built natively in Xcode, utilizing iOS’s built-in AR SDKs and LiDAR capabilities.
