Corey Scott is a software engineer and educator focused on the production-engineering side of Go development — particularly performance optimisation, code quality, and the patterns that separate working Go code from production-grade Go code.
His CourseFlix listing carries two Corey Scott courses: Beyond Effective Go — Part 1: Achieving High-Performance Code and Beyond Effective Go — Part 2: Striving for High-Quality Code. The pair builds on Dave Cheney's classic Practical Go and Effective Go tradition, taking the next step into systematic performance work and engineering practice.
Material is paid and aimed at intermediate-and-up Go developers building production services where the language's performance characteristics matter. For broader content, see CourseFlix's Golang category page.
