During a two-month period, Manh Nguyen enhanced performance and observability across Rust-based systems. For the axiom-crypto/openvm-reth-benchmark repository, he implemented host CPU profiling using samply, improved guest flamegraph generation, and stabilized CI/CD workflows through refined caching and dependency management. In openvm-org/stark-backend, he integrated a Prometheus Metrics Exporter, enabling real-time metrics export and richer observability for the stark-sdk. His work combined Rust, Shell scripting, and YAML to deliver robust profiling, monitoring, and automation solutions. The depth of his contributions is reflected in careful dependency updates, workflow optimizations, and the introduction of asynchronous runtime patterns for reliable metrics collection.
June 2025 (2025-06). Key feature delivered: Prometheus Metrics Exporter integration for openvm-org/stark-backend, enabling metrics export to a Prometheus server and enhancing observability. The implementation includes new dependencies for Prometheus, a run_with_metric_exporter function to configure and start the exporter, and tracing setup with a Tokio runtime to ensure robust monitoring of the stark-sdk. This work lays the foundation for improved monitoring, faster incident response, and better capacity planning through richer runtime metrics. Tech emphasis included Rust, Prometheus, tracing, and asynchronous runtime patterns, with careful dependency management to maintain stability.
