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.

April 2025 performance and reliability improvements for axiom-crypto/openvm-reth-benchmark. Key enhancements focused on profiling capabilities, correctness of profiling artifacts, and CI/CD stability to accelerate benchmarking cycles and improve data quality for performance analysis.
