Graph Protocol indexer components and infrastructure
Role in this project:Back-end Developer
Back-end DeveloperContributions:9 reviews, 36 commits, 11 PRs in 8 months
Contributions summary:Chris implemented and refined core functionalities within the indexer-agent component of the Graph Protocol project.
