Titouan Tanguy enhanced reliability and maintainability across the zama-ai/fhevm and zama-ai/relayer-sdk repositories by addressing simulator timeouts and deployment costs, as well as resolving a re-encryption bug. In FHEVM, he introduced a --max-iter option and updated documentation to mitigate simulator timeouts, while also doubling maximum gas fees in multiple compose files to better align with network participation costs. For the relayer-sdk, he fixed an endianness issue in the re-encryption flow and updated the TKMS dependency. His work demonstrated strong skills in TypeScript, configuration management, and SDK development, delivering targeted improvements with clear technical depth.
