PROFILE
Jonathan Hao
Jonathan contributed to AztecProtocol/aztec-packages by engineering backend features and infrastructure improvements focused on stability, performance, and developer workflow. He refactored cryptographic verification logic in C++ to simplify initialization and enhance consistency, modernized build systems with CMake and Rust to support upcoming toolchain upgrades, and stabilized cross-repo dependencies for reliable WASM and JSON handling. Jonathan also improved CI/CD reliability by enforcing explicit modes and reducing external dependencies, leading to faster, more predictable builds. His work included targeted bug fixes in proof processing and test isolation, resulting in reduced integration risk, clearer alerting, and more robust production deployments across diverse environments.

Jan 1, 2026January 2026 (AztecProtocol/aztec-packages): Focused on stability, CI reliability, and WASM/JSON handling. Delivered three core features with explicit commits that improved Noir submodule stability, CI/build reliability, and JSON/WASM handling. Stabilized cross-repo dependencies, reduced CI flakiness, and ensured stable WASM builds through targeted changes and controlled reverts. These efforts reduce integration risk, accelerate PR validation, and improve confidence in production deployments.

Aug 1, 2025August 2025: Focused on stability, performance visibility, and foundational platform modernization for Aztec Protocol packages. Reverted a disruptive feature merge that impacted AVM benchmarks to restore baseline performance, added operation-count reporting for the default bb command to enable lightweight profiling, and prepared the development environment for clang-18 upgrade with build environment and Dockerfile/AMI updates. These efforts improve reliability for production deployments, reduce profiling overhead in hot paths, and position the project for a smoother upgrade cycle across AMD64/ARM64 builds.
