Daniel Dai is a Software Engineer III at Google with a decade of experience building and optimizing large distributed systems, cloud infrastructure, and high-performance caching. He has a strong backend focus—especially Redis and its multithreaded fork KeyDB—contributing bug fixes, core improvements, and replication test work to widely used open-source projects. His background spans cloud platform engineering at RBC and IBM, where he designed IAM services in Go, improved Redis-backed caching performance, and built CI/CD pipelines for AWS onboarding. Daniel pairs deep systems-level expertise (low-level server headers, macros and crash fixes) with practical cloud architecture and automation skills, and holds a master's in computer science with top grades from Lakehead University.
