Titouan Tanguy enhanced reliability and maintainability across the zama-ai/fhevm and zama-ai/relayer-sdk repositories by addressing simulator timeout risks and deployment cost alignment. He introduced a --max-iter configuration option in TypeScript and TOML to mitigate simulator timeouts in FHEVM, updating the README in Markdown for clarity. In addition, he doubled the maximum gas fee in multiple compose files to better reflect network participation costs. In relayer-sdk, Titouan resolved a re-encryption endianness bug and updated the TKMS dependency, ensuring correct cryptographic behavior. His work demonstrated depth in bug fixing, configuration management, and SDK development within a focused one-month period.
