New in the stores

TacLink

A live tactical map for airsoft and milsim — iOS and Android

A mobile app that keeps the whole squad on one live map, even with the phone locked in a pocket. A Bluetooth mesh between phones covers dead zones, and organizers set up the event on the web. I built and shipped the apps, the backend and the website myself.

About me

I'm Viktor Antunović, owner of AV Solutions j.d.o.o. I build websites, web apps and mobile apps myself, from the first call to launch and maintenance.

For a client I built Rent-a-Clean, a cleaning-booking platform with web, iOS and Android apps. TacLink is my own product on the App Store and Google Play. I meet clients in Rijeka and Istria in person and work with everyone else remotely.

What you can count on

You talk to me directly, with no middleman
The same person writes the code and maintains it
The code is yours and I hand it over on request
A quote after a free first call
A reply by the end of the next working day

Who owns the code

The code I write for you is yours. At the start we agree on one of two ways of working.

I run everything. The site or app runs on my servers and accounts, and I take care of hosting, updates and security. The code is yours and I hand it over whenever you ask.

Everything is in your name. I build and set up on your servers and accounts. You open the accounts following my instructions and pay for the server, domain and other services yourself.

If we stop working together, I hand everything over and leave a transition period for you to move the site or app. Switching from the first way to the second after setup is billed as a migration.

Mobile apps are published under your own developer account on the App Store and Google Play. Google charges a one-time fee for the account and Apple a yearly one. That cost is yours, and you know it up front.

Contact

Have a project or a question? Get in touch. I reply personally by the end of the next working day.
