Red Black Tree is an entirely Serbian software company with ten years of experience in the industry. Our offices are located in Belgrade and Čačak, with approximately 50 team members at the moment.
Our focus is on software development, mostly for clients in the USA, Europe and Asia. We’ve been dedicated to quality assurance, meeting deadlines, professionalism and personal progress. We are a team that provides more than it's promised – whenever it’s possible, which is the case most of the time. That’s how we have acquired high-quality collaborations and long-term projects which provide us with stability.
We value a friendly and positive environment – that’s why we put an extra effort into keeping everything exceptional, from relations with co-workers to the office equipment.
Technologies are carefully selected based on the project requirements. Those are mainly complete systems, which include Mobile apps, Web applications, Backend APIs, databases, containerization and Cloud, which will help you acquire a broad and high-quality knowledge base. We’re not afraid to adapt to modern technologies, just like we did with e.g. Angular, React, Vue.js, as well as .NET Core, Elixir, Kotlin, Python and others before they became widely used and popular.

We are a team of a dozen people, developing a complete software system for the US non-profit, iMentor. Because we know that while talent is equally distributed, opportunities are not, RBT partners with iMentor for the last 5 years in their fight to give every young person a fair chance to graduate college by matching every student with a committed college-educated mentor. Together, we help students in over 50 high schools and 14 cities across the US to fulfill their potential.
The Platform is used by mentees and mentors to communicate, work together on lessons that prepare them for college, and let iMentor’s program managers to supervise thousands of pairs. Our team focuses on design, development, and maintenance of the iMentor platform. We have built a cloud-based SaaS from scratch, with a backend written in Python and Flask using Docker, that queries PostgreSQL, Redis, and MongoDB, and presents using Angular, Swift, and Kotlin.
