Deep Journey
From: Poland

About me
I build mobile and web apps end to end: from design and code to release on Google Play and the App Store. My own product, “Who's Right? — AI Mediator” (React Native + Supabase), is live in both stores and I maintain it in production: AI integration, subscription payments, push notifications, analytics and full GDPR compliance.
I specialize in mobile app MVPs (React Native/Expo + Supabase), web apps and websites (React/Astro), AI integrations and automation (n8n, APIs), and finishing projects started by other developers or built with no-code tools (Draftbit, Lovable, Bubble).
I work transparently: a mockup before any code, a clear scope in the offer and code written with future development in mind. Before that I spent 9 years in game development (game design) and translated EN–PL for the games industry, so the text in your app reads naturally in Polish and correctly in English.
I work fully remotely, with invoicing through Useme.
