Summary
👤
Senior🎓
Top SchoolEleni Stea is a senior graphics software developer with 14 years of experience building and debugging OpenGL and Vulkan implementations for Mesa3D drivers and contributing higher-level graphics features. Based in Greece and currently at Surgical Science, she has a strong FOSS pedigree from roles at Igalia and Canonical, working on everything from compositor subsystems to WebKit and driver testing tools. Her work on Stellarium (improving planet rendering with shaders, normal maps and procedural clouds) highlights a blend of shader expertise and practical optimization for visual fidelity. She runs an active blog and portfolio of hobby projects that showcase experimental graphics algorithms and tooling, reflecting a continuous maker mindset outside of day-to-day work. Comfortable with remote roles, she combines deep low-level GPU knowledge with full-stack contributions to real-time rendering applications. An interesting detail: she has repeatedly turned research and summer-of-code shader work into long-lived production-quality features across open-source projects.

Stellarium/stellarium
Aug 2011 - Apr 2012
Stellarium is a free GPL software which renders realistic skies in real time with OpenGL. It is available for Linux/Unix, Windows and macOS. With Stellarium, you really see what you can see with your eyes, binoculars or a small telescope.

Contributions summary:Eleni made significant contributions to the Stellarium project, primarily focusing on enhancing the planet rendering capabilities. They implemented a shader class and expanded the Planet class to support normal maps, including associated parameters. Furthermore, the user refactored the code to add cloud rendering features, adding code and parameters, and they worked on optimizing the tangent and normal calculations. These changes suggest a focus on improving the visual fidelity and features of the planetarium software.
