Building Android apps at ORF (Austrian national publish broadcasting organization).June-October 2024 (start to launch), developed the ORF KIDS app for Android (https://kids.orf.at).

Mobile development with Android, Compose, and Kotlin (also Multiplatform).

Working with Unity 3D, FMOD, Game.ci, Sentry, building games and custom Unity plugins for content authoring and asset validation. (For hire!)

Lead development of a 2D turn-based battle game in a newly established video game startup. Among other responsibilities, my job comprised of the following tasks:- Building a team of Unity developers, .NET backend developers, and infrastructure developers which collaborated to create the game and necessary infrastructure.- Development of core game functionality with Unity, C#, and Rider, including the turn-bases battle systems and a flexible visual scripting system allowing the creation of custom complex game rules with minimal effort.- Development of a powerful animation system, allowing artists and content creators to import and manage hundreds of unique pixel art characters and monsters.- Setup of multiple gameplay modes (offline single player, LAN-hosted, dedicated server, Cloud gaming using AWS GameLift and Elastic Container Service) using Unity server builds and Fish-Networking.- Development of an automated asset validation pipeline using Unity, C#, Roslyn, and GitHub Actions performing automated code validation as well as validation of game assets (content, images, videos, animations, etc.). The presence of this system enabled our diverse team of developers and artists to collaborate at ease without the risk of breaking code and game content that was already in production.- Development of automated game builds and deployments using Unity, Game.ci, and GitHub Actions. This enabled our team to continuously ship updates in an early access manner, and to shorten the feedback cycles with the game's community (up to 2 mixed content and bug fix updates per week).- Development of important in-house tooling for developers, content creators and artists, including a powerful DI framework, an Aseprite workflow for creating character animations with multiple skins and animations in a single file, isometric world building in a scriptable and ever changing 2D environment, and more.
