Worked on the ethereum/kohaku-extension repository, focusing on restoring stable WebSocket connectivity in the development environment. Addressed a critical issue by reverting the dev server’s WebSocket URL and host configuration to its original state, which prevented development breakages and maintained parity with production systems. This disciplined rollback, executed using git revert, minimized risk and ensured ongoing development velocity. The work emphasized stability and risk mitigation rather than new feature development, supporting rapid iteration for the team. Utilized DevOps and full stack development skills, with JavaScript as the primary language, to deliver a reliable and production-like testing environment for developers.
