Summary
👤
Senior🎓
Top SchoolFyodor Kyslov is a senior software engineer based in the Austin area with deep expertise in embedded systems, RTOS, DSPs, and video compression codecs (AV1, VP9, HEVC, H.264). With over two decades of engineering experience and seven years in senior roles at major tech companies including Google, Apple, Amazon, and Microsoft, he blends low-level performance engineering with production-grade reliability work. His open-source contributions to projects like libvpx and WebRTC show a focus on robustness and real-time encoder optimization—fixing memory/overflow issues and tuning AV1 for realtime use. Fyodor also brought JPEGR decoding capabilities to Skia, demonstrating a knack for pragmatic integration of complex media formats into broad libraries. He is comfortable navigating assembler and DSP toolchains as well as cross-team build and integration challenges, often surfacing subtle runtime bugs before they reach users. Colleagues describe him as a quietly meticulous engineer who prefers preventing failures through careful design and targeted performance fixes.
