Senior🎓
Top SchoolSylwester Mroz is a Senior Software Engineer with 11 years of experience specializing in real-time video and cloud streaming systems, combining deep C++ and C# expertise with Go, JavaScript/TypeScript, and WebRTC. He modernized legacy C++ codebases to C++20, implemented H.265 support in RTSP servers, and built a WebRTC server under a tight three-month deadline while cutting P2P video startup latency from 12 to 3 seconds. Comfortable across the full development lifecycle, he designs architectures, authors technical documentation, writes unit tests, and deploys services using .NET Core, CMake, Azure, and CI/CD practices. His background in technical physics fuels a pragmatic grasp of video codecs, GPU-accelerated decoding, and low-level protocols (RTP/RTSP), enabling end-to-end integrations from camera to browser. Based in Pomeranian Voivodeship, Poland, he is a consistent contributor to production video platforms and a go-to engineer for integrating external CCTV providers and audio streaming into browser clients.
