Our Story

Redtekk was founded by engineer David Ranđelović after years of building software for clients around the world. We started the studio with a simple belief, software should be clear, reliable, and built to last. That is why the people who scope your project are the same people who build it, and we stay on long after launch to keep it working and growing.

No middlemen and no lost messages. You work directly with our lead engineer and lead designer, the same people working on your product every day.

You always know where things stand

Regular demos and honest updates, so you see real progress, not just promises.
