We build web applications and admin panels with React and Next.js, on Node.js backends hosted on AWS. Typical projects are customer portals, internal business tools, marketplace and booking platforms, and the admin interfaces that run a mobile app behind the scenes. How we work: first we agree on the user roles, the core workflows and the scope of the first release. Then we deliver in milestones, with a fixed price for each one, and you can test working versions throughout development. Because the same team builds the web app, the backend and, when needed, the iOS and Android apps, the whole system is designed together. After launch we can maintain and develop the application further, with no lock-in.

We build custom software for businesses: backends and APIs, integrations between existing systems, and complete platforms that combine a web app, a mobile app and an admin panel. Our main stack is Node.js, React and Next.js on AWS, with React Native when the system needs a mobile app. Typical projects: connecting a new mobile app to an existing online store's accounts and order history, building the backend for a marketplace with Stripe payments and identity verification, or developing a business platform that runs in several separate environments. We also take over existing projects from other developers, starting with a review of the code, the infrastructure and the release process. How we work: we agree on the scope and the integrations first, then deliver in milestones with a fixed price for each one. After launch we can maintain and develop the system further, with no lock-in.

We design and build iOS and Android apps in React Native from one shared codebase, together with the backend and admin panel behind them. We have been working with React Native for eight years and have released more than 30 apps with it, including marketplaces, booking and payment flows (Stripe and in-app purchases) and identity verification. How we work: first we agree on the core user flow and the scope of the first release. Then we deliver in milestones, with a fixed price for each one, and you can test working builds throughout development. We prepare the App Store and Google Play submissions, and after launch we can maintain and develop the app further, with no lock-in.
