Ran Engel
Creative Technologist & App Developer  ·  New York, NY

From concept to
shipped software.

I design and build apps, games, and creative tools, combining 13 years of software development with a background in film, cinematography, and visual storytelling.

My work spans product concepts, UX/UI, implementation, release, and ongoing updates — from accessibility and media apps to multiplayer games and AI avatar experiences. I bring that breadth to app development, creative technology, and client projects.

Includes a built-in screenwriting editor, with an AI tutor and co-writer planned for a future version.
