Hi, I'm Dimitrije, a software engineering student at Curtin University in Perth interested in C++ and low-level programming.
A bare-metal STM32L4 firmware that encodes and transmits telemetry packets over UART, paired with a Python receiver that parses frames
Dim-Sim7/PAST-CubeSat-Telemetry-Validation
A client-server order book matching engine written in C++. The server maintains a live book of limit and market orders, matching incoming orders against resting ones using price-time priority.

A lock-free SPSC ring buffer in C++, built across six iterations each introducing
one optimisation: thread safety, cache-line alignment to eliminate false sharing,
acquire/release memory ordering to reduce synchronisation overhead, and cached
index reads to cut cross-core atomic loads. Each version is benchmarked with
perf to measure the impact.
A 3D software rasterizer implemented twice - once on the CPU with OpenMP across 6 cores, once on the GPU with CUDA using tile-based deferred rendering across 262,144 threads.
