David RanđelovićFounder · Lead Engineer
Novi Sad, RSThe founder
Every project on this site leads back to one person.
David Ranđelović is the founder of Redtekk and the engineer behind the work you see here. He spent the years before the studio building software for clients around the world: as an independent freelancer, through Xelpi-IT, a company he founded and ran, and as part of established agency teams.
Redtekk is the next chapter of that work: the same engineer, the same standards, now with a team around him. When you work with Redtekk, David is in the code and on the calls, not managing from a distance.

How we work
Close enough to care. Experienced enough to deliver.
We keep the team compact so the work stays focused. You get direct access, fast decisions, and people who understand both the product and the code.
We treat every project like it has to live after launch.
The goal is not just to ship screens. The goal is to build something stable, useful, and easy to improve when your business changes.
We keep the work simple to follow.
You know what we are building, why it matters, what is next, and where your budget is going.
What matters to us
Good software is not magic. It is care, taste, and engineering discipline.
We do not try to make the process mysterious. We ask good questions, make practical choices, and build in a way that your team can keep using.
Understand before building
We first learn how your business works, what users need, and where the product has to create value.
Design for real people
Good software should feel obvious. We care about clear flows, useful details, and interfaces people can trust.
Build with senior judgment
Every technical choice has a tradeoff. We choose tools and architecture that fit the product, not the trend of the week.
Stay after launch
Launch is not the end. We support, improve, and help the product grow with your team.
