# Jahvix

> Jahvix is a one-person app and website development studio in Ireland: iPhone and Android apps, fast websites and web apps, and the maker of Nana Says No, Dúisigh and NuaIrish.

Jahvix is run by Atul Kumar Jha, an independent developer in Ireland. It does two things: it builds and sells its own apps, and it takes on client projects in app and website development. Clients work directly with the developer, and get a fixed price for an agreed scope before work starts.

How a project starts: 1. Tell me the idea: Send an email with what you want to build and who it is for. A paragraph is plenty. 2. A short call: We talk it through, and I tell you honestly what I would build first and what can wait. 3. A fixed proposal: You get a clear scope, timeline and price before any work starts.

## FAQ
### How much does an app or website cost?
It depends on what it needs to do. After a short call you get a fixed price for an agreed scope, so there are no open-ended hourly bills.

### How long does it take?
A website or landing page takes about 2 weeks. A first version of an app takes about 4 weeks. Your proposal includes the timeline before any work starts.

### Do you build apps for both iPhone and Android?
Yes. I build native apps in SwiftUI for iPhone and Kotlin with Jetpack Compose for Android, and handle the App Store and Google Play submissions.

### Will my website show up on Google and in AI answers like ChatGPT?
Every site is built for it: fast pages, clean headings, structured data, a sitemap, and an llms.txt file that AI assistants can read. Nobody can promise a ranking, but nothing on the site will hold it back.

### Can you redesign or take over an existing website or app?
Yes. I can rebuild an old site on a fast modern stack, keeping your content and your search rankings, or pick up an existing app and keep it moving.

### Who owns the code?
You do. Once the project is paid for, the code, designs and accounts are yours.

### Do you work with clients outside Ireland?
Yes. I am based in Ireland and work remotely, so clients anywhere are welcome.

### Who will I be working with?
Me. Jahvix is one developer, so the person you talk to is the person writing the code, and I have shipped my own apps to the App Store, Google Play and the web.
