PROFILE
Andy Fingerhut
Contributed to the p4lang/p4c repository by delivering backend features, modernizing build and test infrastructure, and ensuring licensing compliance. Over several months, addressed build reliability through CMake configuration, enhanced P4 action control flow, and unified packet processing in Python-based test frameworks. Improved code quality by refactoring for open standards, cleaning up obsolete test data, and aligning licensing with Apache-2.0 requirements. Upgraded CI pipelines to Ubuntu 22.04 and stabilized builds by isolating flaky dependencies. Demonstrated expertise in C++, Python, and YAML, with a focus on backend development, continuous integration, and code maintenance to support robust, maintainable open-source networking tools.

Nov 1, 2025November 2025 — Focused on stabilizing the build for the p4c project by isolating flaky external dependencies. Key action: temporarily disable the p4lang-bmv2 Debian package to preserve build stability while issues are addressed. This prevented unstable builds and allowed continued progress on core development. No new user-facing features were released this month; stabilization and risk mitigation were the priority. All changes were reviewed and signed off appropriately.

Mar 1, 2025March 2025: focused on testing stability, CI modernization, and license compliance for p4c/p4tc. Delivered PTF-based pcap handling in p4tc tests, upgraded CI to Ubuntu 22.04 across pipelines, and updated license metadata to GPL-2.0-only in ptf tests with Apache-2.0 fallback. These changes reduce test complexity, improve reliability, and align with current toolchains and licensing requirements.
