Summary for 2025-08: Delivered a security- and reliability-focused release for Tempesta, notably Tempesta 0.8.1 with security enhancements, attack mitigations, HTTP/2 fixes, and parsing improvements, reinforced by system verification script robustness. Completed packaging and dependencies maintenance, including adding libboost-filesystem-dev, upgrading kernel headers/images, and simplifying Debian packaging rules, with kernel version compatibility updates for verification scripts. Resolved a config parsing issue in the troubleshooting script to reduce deployment friction. These efforts improved security posture, reliability, and maintainability, enabling smoother deployments and cross-environment compatibility. Demonstrated skills in security engineering, low-level packaging, Linux kernel/version management, and robust parsing/verification workflows.

January 2025 across tempesta-tech repositories delivered reliability and maintainability improvements with measurable business impact. Key features improved logging fidelity and test coverage, while infrastructure enhancements reduced deployment risk and prepared the teams for upcoming JA5T work.

December 2024: Implemented comprehensive JA5 Hash Filtering Test Coverage for Tempesta Firewall, validating JA5 fingerprint filtering across TLS versions, cryptographic curves, and cipher suites; added tests for invalid configuration values and restart/reload behavior to ensure robust filtering under config changes. Work anchored by commit 3a3e79c3a516ea2127b00eef3b305bcdcab5611a (ja5 filtering), improving reliability, security posture, and deployment confidence.
