How we work

A clear process with short cycles and continuous visibility. One person leads the project from the first call to launch, and AI speeds up development under the review of an experienced engineer.

  1. Discovery

    We define goals, scope and priorities. Before work begins, you get a timeline and a price range.

  2. Prototype

    We build a clickable prototype to confirm the direction early, while changes are still easy.

  3. Development

    We develop in short cycles, with regular releases you can test and review.

  4. Delivery

    We launch, hand over the code and documentation, and continue with maintenance and upgrades.

Senior engineering

More than ten years building applications and systems, from idea to production. I have worked for large companies, institutions and startups, and the architecture is considered from day one.

AI tools accelerate development and testing, and an engineer reviews every result. Speed without compromising on quality.

Direct communication

You speak with the person who plans and builds the project. No middlemen, and no information lost between teams.

Your code, your ownership

Source code, access and documentation belong to you. No lock-in to a proprietary platform.

Mobile app: native or React Native?

Native or cross-platform mobile development: differences in cost, speed and user experience, and when React Native with Expo is the right choice for iOS and Android.

Frequently asked questions

How much does a website, app or software cost?

Websites start from €400, web and mobile apps from €1,800, and custom software from €600. The hourly rate starts from €35. The final amount depends on complexity: the number of screens and features, integrations, design and security. After a short conversation you get a free estimate and a price range, with no obligation. Prices are indicative and exclude VAT.

How long does a build take?

A simple website can be ready in a few days. More complex sites, and web and mobile apps, take from a few weeks to a few months depending on complexity. We agree the exact timeline after discovery.

What does AI-driven development mean?

We use AI tools to write and test code, so repetitive work gets done considerably faster. Architecture, decisions and the review of every result are handled by an experienced engineer, so quality does not depend on what the AI suggested.

Do you work with clients outside Zagreb?

Yes. We work remotely with clients across Croatia and the European Union. Meetings are in person in Zagreb or over video call.

Can I get a mobile app together with my web application?

Yes. React and React Native share part of the logic, so a web and a mobile app together can cost less than two separate projects.

Do you offer maintenance after launch?

Yes. After launch we offer maintenance, upgrades and technical support by agreement.
