Manh Dinh

Worked on performance, observability, and CI/CD improvements across openvm-org/stark-backend and axiom-crypto/openvm-reth-benchmark. Delivered a Prometheus metrics exporter for stark-backend, enabling runtime metrics collection and export via Rust’s async patterns and Tokio, with careful dependency management to maintain stability. Enhanced reth-benchmark by implementing host CPU profiling using samply, improving artifact correctness and profiling data quality. Addressed guest flamegraph generation issues by updating dependencies and refining artifact paths. Stabilized CI/CD workflows through improved caching strategies and workflow configuration, leveraging Rust, Shell scripting, and GitHub Actions to accelerate benchmarking cycles and ensure reliable, high-quality performance analysis and monitoring.

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.
