Mobile app development studio
Complete mobile products.
From idea to App Store.
You bring the idea. We deliver the rest — product design, iOS and Android apps, backend, and launch. A finished product, live on both stores, built by a studio that ships its own apps the same way.

We keep client names private by default — out of courtesy to the businesses we built for. On an intro call, we’ll walk you through exactly what we built.
What we deliver
One team, the whole product.
Every layer of a mobile product, built and owned by the same people. No handoffs, no gaps between design and engineering.
Design & UX
Product design, not just screens. We shape the flows, the interactions, and the details users actually feel — from first wireframe to a polished, on-brand interface.

Apps that feel right on every device — native Swift and Kotlin when the product demands the full platform, or one Flutter or React Native codebase when speed and budget matter most. Smooth, reliable, and tuned to the device either way.

The engine behind the app: authentication, data, payments, notifications, and integrations. Built to scale with your product and stay observable in production.
Node · Firebase · PostgreSQL · cloud infrastructure

We take it across the line: App Store and Google Play submission, release pipelines, monitoring, and ongoing support after launch. The product keeps running — and improving.

Alexandru MardareFounder & Lead Engineer
Alexandru has been building mobile apps for over seven years — four of them on Raiffeisen Bank’s iOS app. Through Codeck Core he has shipped every product on this site end to end: client builds delivered under contract, and Petovi, our own pet-care app, live on both stores. When you write to us, he’s the one who answers — and the one who builds.
