Roley — Make a Movie!: Multi-video recorder for kids
Built the MVP end to end. The client changed course to an offline business just before launch.
Make a movie in four steps
The screenshots on this page are a portfolio re-imagination I built later; the original client's branding wasn't mine to share.

Scripts
Physical craft boxes of scripts, props and costumes pair with the app.
Recorder
The digital recorder films one scene at a time.
Processing
An ffmpeg.wasm video pipeline stitches the clips into a finished movie, with intro and ending credits and 50+ transitions.
Watch
The finished movie.
What I built
Multi-video recorder for kids. Pick a script, record scene-by-scene, and the app stitches the clips into a finished movie — with intro/ending credits and 50+ transitions. Full stack: SvelteKit app, ffmpeg.wasm video pipeline, Postgres, AWS S3 + SES, Slack + Mailchimp webhooks. Paired physical craft boxes (scripts, props, costumes) with a digital recorder so the founder's vision of physical play + digital creativity just worked.

Anton was a terrific partner to me in developing an MVP of a web app I've been dreaming of for ages. He is a highly skilled developer, a super resourceful problem-solver, and a conscientious and communicative collaborator. Hiring someone you don't know to build your idea can be scary, and I'm grateful I found my way to Anton. If you're looking for a fast, expert, transparent guide to help you bring a big idea to life, working with Anton is a great choice.
Anton has been a terrific collaborator and thought partner to me. In addition to his expertise, I particularly appreciate his real-talk, practical advice on the smartest options to move forward with a new idea or navigating an issue. He's a great communicator and an easy collaborator.
