Uroš Jakovljević
Technical Architect & AI Systems Builder. Founder of Wolrix.
One person owns every Wolrix build — spec, schema, code, deploy. This is who that person is.

Real clients. Real contracts. Real reviews. The full track record is public.
“UJ is a top member of our team. He is extremely efficient and works well with multiple team members. His knowledge of the web development tools is excellent.”
“Project was completed ahead of time and outperformed the original expected outcome. Outstanding work and will continue to work on future projects.”
“Uros is a pleasure to work with. He is dedicated, enthusiastic, solution-orientated and highly competent. This was a reasonably complex project that required creative problem solving and a high level of collaboration. Uros was the perfect partner.”
Why one lead beats a team for $10K-$50K builds.
A typical $40K agency build loses 40-60% of engineering hours to coordination overhead, status meetings, hand-offs, and “alignment.” A one-lead shop converts the same budget directly into shipped code. The trade-off: you can't scale the team mid-project. So Wolrix scopes for builds that fit one senior engineer working 4-8 weeks. If your project doesn't fit that shape, we'll tell you in the intro call instead of taking the contract.

30 minutes. No discovery dance. Either Wolrix is a fit or it isn't — you'll know by the end of the call.
