  • BDD (Behaviour Driven Development)

I had asked Kevin from Vibecoder for a dashboard, and he delivered a dashboard in React of impeccable quality (making one wonder if it was really vibe-coded). Everything was thought out to the smallest detail: clean and scalable architecture (clean architecture), complete test coverage, adherence to the provided design (pixel perfect), and delivery slightly ahead of schedule. In addition to the technical quality, Kevin was proactive, very professional, and friendly throughout the project. I highly recommend him.
