PROFILE
Kristof Hetzl
Over four months, contributed to the ArweaveTeam/arweave repository by re-architecting the rate limiting service into a standalone Erlang application, improving modularity and scalability for backend systems. Enhanced API rate limiting with granular configuration and startup reliability, and strengthened observability by expanding Prometheus metrics and clarifying documentation. Maintained repository hygiene through targeted cleanup of deprecated services and workflows, and paused the Bug Bounty Program via focused README updates to support governance review. Demonstrated expertise in API development, middleware design, and DevOps practices, leveraging Erlang, YAML, and Prometheus to deliver maintainable, resilient infrastructure and transparent project communication for stakeholders.
