Marcin developed and enhanced gameplay features for Goob-Station and Frontier Station-14, focusing on networked game mechanics and visualization improvements. He implemented automated wireless connectivity for conveyor systems and sub-floor reveal functionality, reducing manual configuration and improving reliability. Using C#, YAML, and an entity component system, Marcin addressed both backend and client-side challenges, such as synchronizing Dragon Rift color dynamics across clients through event-driven updates and network handlers. His work ensured visual consistency and accurate state representation between server and client, while thorough documentation and changelog updates improved maintainability. The solutions demonstrated depth in client-server architecture and game development.
