What we build with.
We choose the technology for the project: fast, easy to maintain and still around in two years.
Front end
TypeScript, React and Next.js, plain JavaScript for smaller projects, Tailwind or plain CSS, PWAs, WebAssembly and WebGPU.
Back end
Node.js with Express or Fastify, Python with Flask or FastAPI, Go for heavy loads, REST and GraphQL, Stripe and Paddle.
Data
PostgreSQL, Firestore or MongoDB, Redis for caching, S3 or GCS for files, Cloudflare D1 and R2.
Infrastructure
Cloudflare Workers, Firebase and Google Cloud, Vercel or Netlify, AWS, Docker and automated deploys.
Priced in stages.
On larger projects you don't pay everything up front. Each stage is paid 50% at the start and 50% on delivery, and after it you have a working product and decide whether we carry on.

Questions.
What is a web app?
A site that does work instead of just showing information. Users sign up, enter data and see dashboards. Think of a CRM, a booking system or inventory software.
Do you maintain the app after delivery?
Yes. For the first 30 days we fix bugs for free. After that, for apps we recommend the Scale plan at €300 a month: updates, monitoring and 16 hours of work on new features.
Can you take over an existing project?
Yes. We review the code (€600), give you an assessment and a price to continue or rework it. If the code is in bad shape, we'll tell you it's better to start again.
How long does it take?
A first version in 6–10 weeks, a mid-sized project in 3–5 months, and a large platform in 6 months or more, split into stages.
