At ConnectWise / Axcient, I optimized server source code and SQL queries, making critical business operations 20x faster. I also architected multi-threaded data synchronization layers for x360Sync using C++17 and Boost.

I integrated Protocol Buffers to streamline cross-component communication and refactored legacy components to improve code reuse and testability. I also contributed to technical interview loops for senior candidates.

At Nutanix (Frame), I developed low-latency backend logic for the MF2Server product line and optimized multi-threaded data structures to eliminate thread contention. I used template metaprogramming and design patterns to create reusable interfaces and make server modules easier to unit test.

My work has also included adding traffic signs to infrastructure for an autonomous vehicle project at Syrmia, designing deterministic driving APIs for BMW at RT-RK Automotive, and developing embedded C++ and Qt software for AVL DiTest at Comtrade Solution Engineering. I’m a founding member and speaker at C++ Serbia, where I’ve given talks on technical interviews and testing.
