I don't just use libraries. I build the ecosystem.Architect of Summon, Materia, and Sigil. I specialize in building high-performance graphics runtimes and developer tools that bridge the gap between JVM backends and modern UI.

The "Unfair Advantage"
Systems ArchitectureMost candidates can build a feature. I build the framework. I understand API surface area, backward compatibility, and the complexities of maintaining a full stack (UI + Engine + Shaders) used by others.
The Graphics/UI BridgeI solved the "Hard Problem" of declaratively managing 3D state. By building Sigil (a React-Three-Fiber equivalent for Kotlin), I proved I can translate complex imperative graphics pipelines into ergonomic, reactive APIs.
True MultiplatformI don't rely on wrappers. I write logic that compiles to Wasm, Native (Metal/Vulkan), and JVM. I understand the memory models and concurrency challenges of every target platform.

Ideal Role CriteriaI am looking for:
Engineering ChallengesRoles involving Graphics Runtimes, Tooling Infrastructure, or Core Product Architecture.
CultureTeams that value "Deep Work," open-source contribution, and high-quality documentation.
LocationActively seeking relocation to London, Berlin, Amsterdam, or US Tech Hubs. Open to remote.
