Websites, apps and AI assistants that do the work.

A site that reassures, an application that holds up, an assistant that answers correctly. We always start with the question that has a number in it, and we end with something in production that you can evolve without us.

Each tile queries a public source when you open the page. If a source does not answer, the tile says so; it never makes anything up. That is exactly what we expect from your dashboards.

We do not sell models for their own sake. We start from the data you already have, measure what a simple model adds, and only ship what survives validation.

• Forecasting prices, demand, lead times
• Risk and priority scoring
• Classification and automatic sorting
• Anomaly detection
• Statistical validation and backtests

• Quantitative trading terminal

  Real-time connectors to two exchanges, statistical certification protocol, continuous execution on a VPS.

1. Scoping

   One call, a written brief with the problem in your words, a quote that says what is in and what is out.

2. Build

   A demo every week, on a real address. A decision log: what we chose, what we rejected, why.

3. Delivery

   The code, the documentation, a handover session and the honest list of what remains open.

4. Review

   Within 48 hours: measured results, what took longer than planned, what you can reuse elsewhere.

5. Support

   Maintenance, improvements, on-call if the system runs continuously.

The calculation starts from 92 € per hour of production. A billed day at 550 € covers 6 hours of actual work; the rest is coordination we do not bill.
