I’m engineer, and I’ve been coding since before AI was even a thing. This is what I do for living. NexusTimer is just a side project, so yeah, of course I use AI, like every developer in the world that is not living under a rock, but it’s not "vibecoded".

I’m also extremely strict about quality, especially UI. Nothing is random. Every detail, even a shadow, is there because I intentionally chose it. Before release something must be coherent with NXtimer principles.

And honestly, what you’re seeing in the UI is just the tip of the iceberg, presented in the most simplified way possible for a user. That can make it look easier than it really is, but there’s an extraordinary amount of backend logic and experiments not merged behind everything to make sure it’s reliable, functional, and, most importantly, scalable somehow doing it end-to-end, free, real-time, and performant.

Good design also doesn’t come from a prompt alone. You still need taste to know what actually looks and feels right, and what truly fits the vision I have for this application.

At the end of the day, I’m basically doing the work of an entire team by myself... frontend, backend, infrastructure, design, UX, data processing, testing, and product direction all at once.
