We build modern software & AI products
Aystack is a development studio based in Serbia, helping companies design, build and ship reliable web applications and AI-powered solutions — from first idea to production.
A focused, senior-led studio
Aystack is led by Aleksandar Jovanović, a software engineer who works hands-on with every client. No middlemen, no bloated teams — just clean engineering and clear communication.
We partner with founders and businesses to turn ideas into well-crafted products: fast, maintainable, and built to scale.
