Worked on reliability and cost improvements for the zama-ai/fhevm and zama-ai/relayer-sdk repositories, focusing on bug fixing, configuration management, and SDK development using TypeScript, TOML, and Markdown. Addressed simulator timeout issues in FHEVM by introducing a --max-iter option and updating documentation, while also adjusting maximum gas fees in multiple compose files to better align with network participation costs. In the relayer-sdk, resolved a re-encryption endianness bug by updating the TKMS dependency and refining code for maintainability. These efforts enhanced deployment stability, reduced operational risks, and improved the overall developer experience through targeted configuration and documentation updates.
