What types of applications do you develop?

We cover the full spectrum: internal business web applications, SaaS, dashboards and back-offices, startup MVPs, iOS/Android mobile applications. Each project is custom-built to your real needs.

How long does it take to develop an application?

It all depends on complexity. A functional MVP can be delivered in 6 to 10 weeks. A full business application typically takes 3 to 6 months. We systematically break work into sprints to deliver value as early as possible.

What technologies do you use?

Frontend: Next.js, React, Tailwind CSS and TypeScript. Mobile: React Native or native depending on needs. Backend: Node.js, Supabase, PostgreSQL. Modern, high-performance stacks that are easy to evolve.

How do you ensure my application's security?

Robust authentication, encryption of sensitive data, granular permissions, GDPR compliance, regular security audits and European hosting. Security is built in from the design stage, not bolted on at the end.

What happens after production deployment?

We support you for the long term: monitoring, technical support, feature additions, optimisations, version upgrades. You have a dedicated contact and clear timelines for each evolution.
