Hi, I’m Yevhen “Jack” Sydorenko, a senior software engineer with 21+ years of experience spanning system architecture, software development, game development, and simulation systems. I specialize in Unity DOTS (ECS, Jobs, Burst), C# architecture, and high-performance software. I’ve created tools and frameworks such as StoryTailor and HexTerrains, and I’m passionate about scalable code, optimization, and building creative development tools.
I’ve led teams of 3–10 developers, defined architecture and pipelines for large Unity projects, and mentored colleagues across disciplines. I enjoy solving complex problems, delivering polished experiences, and empowering others through robust tooling and well-structured codebases.
