We are a small team of engineers and designers from Belgrade, Serbia. We help people turn ambitious ideas into software that is clear, reliable, and ready to grow.
Redtekk is led by two people who stay close to the work from the first sketch to the shipped product. No account managers in between, no handoffs to strangers.
David is the engineer behind the work you see on this site. 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.
When you work with Redtekk, he is in the code and on the calls, not managing from a distance.
Nikolina leads design at Redtekk. She shapes how a product looks, feels, and flows, so the interface is clear for the people using it and practical for the people building it.
She works side by side with David from the first sketch to the shipped screen, which keeps design and code pulling in the same direction.
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.
No layers of account managers. No handoff maze. You get engineers and designers who understand the work and stay close to the details.
The goal is not just to ship screens. The goal is to build something stable, useful, and easy to improve when your business changes.
You know what we are building, why it matters, what is next, and where your budget is going.
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.
We first learn how your business works, what users need, and where the product has to create value.
Good software should feel obvious. We care about clear flows, useful details, and interfaces people can trust.
Every technical choice has a tradeoff. We choose tools and architecture that fit the product, not the trend of the week.
Launch is not the end. We support, improve, and help the product grow with your team.
Bring the idea. We will help shape it, build it, and make it ready for the people who need it.
