Core Protocol Engineer specializing in the architecture, performance, and security of core blockchain infrastructure. My experience is centered on building and maintaining high-throughput distributed systems that handle millions of daily transactions. At Polygon Labs, I served as a core contributor to the consensus (Heimdall) and execution (Bor) layer. In my spare time, I like to browse through research papers on developments in BFT systems, watch films and read.
