Worked on the elastic/opentelemetry repository to deliver targeted documentation improvements supporting GenAI telemetry and LLM observability use cases. Focused on enhancing onboarding and integration readiness by authoring detailed Markdown and YAML documentation, including a new use case guide for EDOT-LLM instrumentation. Improved documentation readability and navigation with emoji-based status indicators, fixed broken links, and standardized feature versioning across language SDKs. Addressed symbol inconsistencies and clarified feature availability, reducing onboarding friction and supporting better release planning. Demonstrated skills in technical writing, documentation engineering, and cross-language consistency, with careful attention to detail and traceable, versioned updates throughout the two-month period.
