During December 2025, Arunkumar Karthikeyan updated the vendasta/api-gateway-docs repository to align all documentation with the new Reputation AI branding. He systematically replaced references to "Reputation Management" with "Reputation AI," ensuring consistent messaging across customer-facing materials. Using Markdown and JSON, Arunkumar applied version-controlled content updates that improved clarity and reduced potential support issues. His work focused on documentation governance and required close collaboration with product and marketing teams to maintain branding accuracy. While no bugs were addressed, the feature delivered clearer onboarding and product messaging, demonstrating attention to detail and proficiency in technical writing and API documentation practices.
