Before you write
The answers people usually need before a first call.
How much does a custom application cost?
Projects start from €10,000 for something focused and scale from there with complexity, integrations and timeline. You get a fixed price in writing after discovery — we do not send an estimate that quietly grows.
How long does a typical project take?
A focused MVP or smaller web application runs 4–8 weeks. Platforms with several integrations, a mobile app or AI features usually land between 8 and 16 weeks. Discovery produces the actual dates before any code is written.
Do you work with startups or enterprises?
Both, though the work looks different. With startups we are usually building the first version and arguing about scope. With established companies it is more often modernising something that already carries real load and cannot go down.
What is your development process?
Two-week sprints, each ending with working software on a staging URL and a demo you attend. CI/CD handles testing and deployment. If a sprint goes sideways you hear about it that week, not at the end.
Do you provide ongoing maintenance?
Yes — monthly retainers covering monitoring, security updates, performance work and new features. It is also fine to stop. Every project ends with handover documentation whether or not you keep us on.
What technologies do you specialize in?
React, Next.js and TypeScript on the frontend; Flutter, Swift and Kotlin for mobile; Node.js, Laravel, Symfony and Fastify on the backend; AWS, Docker and Vercel for infrastructure; OpenAI, Anthropic, OCR and LangChain for AI work.
Where are you located?
Romania — CET/EEST, which overlaps most of the working day in Europe and the morning in the US. Clients are global and the entire engagement works remotely.
Do you build mobile apps?
Yes. Flutter for most work, since one codebase covers iOS and Android at native performance. Swift or Kotlin when a project genuinely needs platform-specific behaviour. Offline support and push notifications come as standard.
