I build and launch AI-powered full-stack products from client requirements to production.

What I'm looking for

I'm looking for remote or hybrid EU opportunities where I can own full-stack AI product delivery, work closely with clients, and turn ambiguous requirements into production software.

I've built AI voice and speech-technology solutions for enterprise healthcare and service clients including SYNLAB, RMC, and Xmed360 at BLCKS Software. I delivered backend integrations and client-facing interfaces using Angular, NestJS, and Azure.

I took Flinkit from concept to public launch, helping it reach #2 in Product Hunt's daily ranking. I've also shipped production features for Wingman, a travel app with 100,000+ downloads, and delivered full-stack work for the award-winning proptech platform Propertizer.

Across five client projects, I've moved quickly between stacks and domains, turning changing business requirements into technical decisions and earning an early promotion from junior to medior.

As an independent developer, I deliver complete web applications from API design and data modelling through frontend development and deployment. I've built payment flows, CRUD dashboards, AI chat interfaces, Shopify storefronts, and React Native mobile features in both Hungarian and English.
