Summary
🤩
Rockstar🎓
Top SchoolDaniel Sperl is a senior software engineer and founder with 16 years of experience building game and UI frameworks from Austria. As co-founder of Gamua he authored the Sparrow and Starling frameworks, contributing deeply to their rendering, UI components and particle systems used by cross-platform game developers. He blends front-end craftsmanship with performance-oriented engine work—fixing UV calculations, optimizing rendering paths and adding features like rotation and robust event dispatching. Currently at SchoolCraft, he continues to bridge product needs and low-level graphics engineering, drawing on a background in media technology and a history at studios including Quanmax and funworld. An interesting detail: his open-source tweaks often focus on practical demos and tooling (e.g., Particle Designer compatibility), showing a strong attention to both developer experience and runtime efficiency.
