Xinding Wei

Wei Xin Ding developed core verification and benchmarking infrastructure for the openvm-org/stark-backend and axiom-crypto/openvm-reth-benchmark repositories, focusing on scalable zero-knowledge proof systems. Over seven months, he implemented backend verification logic, persistent chip state management, and reproducible build pipelines using Rust, CI/CD, and dependency pinning. His work included optimizing symbolic computation with caching, refactoring configuration layers, and enabling fixture-based profiling for targeted performance analysis. By improving documentation accuracy and integrating SDK renaming, he enhanced maintainability and onboarding. The engineering approach demonstrated depth in backend development, system integration, and performance optimization, resulting in stable, traceable, and scalable cryptographic workflows.
