Top expert inCross-Platform Game Development and Engine Technologies
Mario Zechner is a seasoned software engineer and entrepreneur with 16 years of experience building cross-platform tools, game frameworks and compiler technology from Graz, Austria. As creator and lead of libGDX—the leading Android game development framework—and contributor to notable projects like packr and Spine runtimes, he blends deep systems-level C++/Java work with test automation and cross-platform integrations. He has led engineering teams, mentored startups at Science Park Graz, and helped bring RoboVM from prototype to acquisition, demonstrating both technical depth and startup-savvy. Currently running Earendil and self-employed on projects spanning VR, compilers and skeletal animation, he pairs hands-on coding with product-thinking and a penchant for quirky, user-facing creations. An author and long-time open-source maintainer, he’s equally comfortable refactoring engine internals as shipping cross-OS packaging and web-enabled native libraries.
