December 2024: Implemented foundational HTTP/2 refactor in google/quiche, reorganizing core components and introducing a reusable chunk-extension validation helper to improve maintainability and future-proofing. Also expanded test coverage with unit tests for both nghttp2 and oghttp2 adapters to ensure consistent protocol error handling when content-length is undershot, reducing interoperability risk across adapters. The work lowers maintenance costs, improves reliability of HTTP/2 handling in diverse environments, and strengthens the repository's modular architecture. Demonstrated skills in code refactoring, modularization, test-driven development, and cross-adapter compatibility testing, with a clear focus on delivering business value and reducing risk."
