Summary
👤
Senior🎓
Top SchoolIgor Kobzar is a Senior Systems Engineer Generalist with nine years of recent experience and over two decades of deep systems and networking expertise, currently driving HTTP/2 performance and load balancing at Facebook. He excels in C++14, low-level Linux/Unix programming, real-time and kernel work, and has a proven record of squeezing scale and reliability out of complex distributed systems—from WAN optimization across 32-core appliances to carrier-grade firewall and PKI projects. Igor is a pragmatic problem solver who routinely diagnoses hard-to-reproduce crashes, automates analysis, and uses sanitizers, custom allocators and gdb-python tooling to cut debug time. An active contributor to Facebook’s popular proxygen HTTP library, he has delivered performance fixes, priority-queue optimizations and observability enhancements for HTTP/2 flow-control pathologies. He combines systems thinking with an appetite for machine learning and security, bringing both algorithmic rigor and hands-on engineering to reduce runtime errors and operational cost.

Contributions summary:Igor primarily focused on performance improvements and debugging within the Proxygen HTTP library. Their contributions centered around identifying and addressing session stalling issues caused by flow control mechanisms in SPDY/HTTP2, including the addition of metrics and tests to monitor these issues. They also worked on optimizing the HTTP2 priority queue implementation and adding features to measure byte-weighted average active connections. Moreover, the user implemented initializer lists for HTTPHeaders, improved code structure and debugging.
