Worked on the erlang/otp repository to enhance documentation around JSON-to-Erlang data mappings, specifically clarifying that a JSON Array should be represented as an Erlang list. Focused on improving developer onboarding and reducing ambiguity by providing explicit guidance for handling JSON input and output within OTP. Leveraged expertise in Erlang and technical documentation to create a traceable, maintainable update that supports cross-language interoperability. The work addressed a common source of confusion for developers integrating JSON with Erlang systems, ensuring future maintainers and contributors have clear expectations for data types and improving the overall consistency of the codebase’s documentation.
