Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

I'm a professional programmer with over 10 years of experience in web applications, video games, and desktop apps. I have two years of experience leading teams (plus about five more years with my non-commercial side projects). I excel in C#, Unity, and a wide range of third-party packages, frameworks, and libraries. I value clean architecture, design patterns, and robust refactorization to keep codebases maintainable. My most successful project to date is the match-3 game Spire Blast, which reached the top 10 on Apple at one point. I also enjoy building tools and prototypes to explore new ideas, such as Voxels for math and procedural generation showcases and DataViewer, a small WPF app I built in a week.…I'm a professional programmer with over 10 years of experience in web applications, video games, and desktop apps.
