Worked on the openfhe-development repository to enhance cryptographic validation by implementing a custom epsilon in floating-point equality checks, addressing precision issues in result verification. This update improved the reliability of cryptographic computations, particularly in contexts sensitive to minor numerical discrepancies. Additionally, managed the release of OpenFHE 1.2.4, which included enhancements to STL thread support and fixes for identified CVEs, thereby strengthening both security and multi-threaded performance. The work involved C++ for core development, Markdown for documentation, and applied skills in cryptography, release management, and unit testing to ensure robust, well-documented, and secure software delivery within the project.
