Worked on the golang/tools repository to deliver an enhancement to the Go Language Server, focusing on improving code completion for generic functions. Developed a feature that leverages polymorphic type inference to analyze call-expression context, resulting in more accurate and context-aware parameter suggestions for Go generics. This approach required a deep understanding of Go, generics, and the Language Server Protocol, integrating type inference techniques to support downstream tooling. The work addressed the challenge of providing precise completions for generic code, ultimately streamlining the developer experience and reducing the time required to write correct generic functions in Go-based projects.
