Which technologies do you use for web apps?
Our delivered web platforms use React and Next.js on the front end, with PostgreSQL, Redis and cloud services such as AWS behind them. We choose per product.

Can you build a SaaS product?
Yes. See AI SaaS development and our construction SaaS case study.
How long does it take?
It depends on scope, platforms and integrations. We agree milestones up front and review a working version at each one.

Ownership, licensing and handover are agreed in the contract before work starts.
