How it works

From first call to launch

  1. Intro call

    A short call about what you need, who it's for and what a good result looks like.

  2. Proposal

    A written plan with the scope, timeline and cost, so you know what you get before anything starts.

  3. Build

    Work in small steps on a preview link you can open at any time, with regular check-ins.

  4. Launch and care

    Going live, handing over everything you need, and fixes and updates afterwards if you want them.

About the founder

Vuk Aranđelović

Full stack developer, founder of WolfStack

I'm a full stack developer from Serbia, and I like building things from the database up.

Most days that means Next.js, NestJS, GraphQL and PostgreSQL. I pick up new tools quickly and I'm happiest in the terminal.

With WolfStack, you work directly with me, from the first call to launch and beyond.
