Rockstar🎓
Top SchoolElijah Semyonov is a software engineer with eight years of experience specializing in iOS development, low-level Metal rendering, technical art and AR interaction design. Currently at JetBrains and founder of AstrotouR, he combines production-grade app architecture with custom rendering engines and shader work to recreate complex astronomical phenomena on low-power mobile GPUs. Proficient in Swift, Kotlin, C++ and Objective-C, he routinely tackles performance bottlenecks, multithreaded systems and serialization across REST and binary protocols. Past roles show a track record of dramatic performance optimizations, legacy migrations to Swift, and establishing testable MVVM-C architectures. He also designs offline tooling, domain-specific markup languages and content pipelines, bringing both product direction and hands-on engineering to projects. Based in North Holland, he blends analytical rigor with a creative, almost artistic approach to problem solving.
