Summary
👤
Senior🎓
Top SchoolMarcus Spangenberg is a senior software engineer based in Sweden with 11+ years building performance-critical systems across realtime media, embedded platforms, and high-throughput networking. He designs and implements low-latency C++ systems—ranging from selective forwarding media servers and RTP/SDP negotiation to lock-free data structures and custom allocators—while emphasizing maintainability, testability and measurable performance. Marcus has led architecture and delivery for RTC products in cloud container environments and driven platform ports and low-level optimizations for mobile GPUs and ARM/Neon. Comfortable across Linux, iOS, macOS, Windows and Android native stacks, he blends hands-on implementation with team leadership and pre-study planning. A pragmatist who prefers proving designs through performance analysis, he often surfaces non-obvious trade-offs in concurrency and memory that materially improve system throughput and reliability.
