Answers to the questions we hear most.
Short and honest. If yours is not here, ask us directly.
Redtekk is a software development studio based in Novi Sad, Serbia. We design, build, and support custom software: websites, web applications, online stores, and AI features, for clients around the world.
The people you talk to. Redtekk is a small senior team led by founder David Ranđelović, who stays in the code and on the calls throughout the project. Nothing gets handed off to juniors or an outsourced team.
With a conversation. You tell us what you are building, we ask questions, and you get an honest assessment of the scope and approach before any commitment. Email hello@redtekk.com or schedule a meeting through the site.
Angular, React, Vue, and TypeScript on the frontend. Node.js and Laravel on the backend. PostgreSQL, MySQL, and MongoDB for data, plus Shopify, Stripe, Webflow, Figma, and modern AI tooling. We pick the stack that fits the project, not the other way around.
Yes. Launch is a milestone, not the end of the engagement. We handle support, monitoring, fixes, and improvements, and most of our client relationships continue well past the first release.
Yes, most of our work is international. We are based in Novi Sad, Serbia, work remotely with clients around the world, and communicate in English.
Let's build something that lasts.
Whether you're launching a new product, improving an existing one, or looking for a team you can rely on long-term, we're ready to help.
