À propos de moi
I'm a React Native and full-stack TypeScript developer from Estonia, freelancing since 2021. Since 2024 I've been the lead developer of Cocopine, a parental control app for YouTube that runs at 99.9% crash-free with 4.5 stars on the App Store and Google Play. Most of my work is fixing apps that got stuck: crashes, broken builds, store rejections, or an AI-built app that works in the demo but breaks for real users. Send me a short description of the problem. I'll tell you what's wrong and what it costs before you order.... Plus d’infos

Cocopine

Lead Full-Stack Developer

Cocopine • Temps plein

Oct 2024 - Present • 2 yrs 1 mo

Lead developer of a parental control app for YouTube on iOS and Android. I took it over a year after launch while it kept failing technically, and made it stable: 99.9% crash-free, 4.5 stars, a release every month, video playback failures down to 2-3%. I own the React Native (Expo) app with parent and child modes and the Node.js backend with Fastify, PostgreSQL, Redis and BullMQ on AWS, plus tests, CI/CD, monitoring and the App Store and Google Play releases with EAS.

Worked with 5+ startup clients across the full cycle, mostly as the only engineer. Took over a React Native app live on the App Store and Google Play at a mature stage with heavy technical debt, and brought its performance and unfinished features back under control. Also built React Native apps and Next.js platforms on Firebase and Supabase, including a multi-tenant platform for US nursing homes.
