Cristian worked on the Jumping-Jack project in the CITM-MOBILE-DEVICES-TERRASSA repository, focusing on improving rendering stability and asset management using Unity and C#. During this period, he addressed a z-fighting issue in the Level1 scene by programmatically disabling the m_Enabled property on multiple SpriteRenderers, which resolved depth conflicts and improved visual consistency. Additionally, Cristian enhanced asset management by introducing a new assets meta file to streamline bundling and tracking. While the work was limited in scope, it demonstrated a targeted approach to debugging and maintenance, emphasizing practical problem-solving within the context of game development and Unity engine workflows.
