June 2025: Focused on expanding test coverage for CREATE2 contract deployment in the RPC tests suite. Delivered a new integration test validating ots_getContractCreator behavior under CREATE2, improving reliability of contract creator derivation and preventing regressions in production deployments. No major bugs fixed this month in the rpc-tests scope.

In May 2025, delivered Cloudflare R2 CDN support for Snapshot Data in erigon-snapshot, enabling data fetch from Cloudflare R2 alongside GitHub. Refactored URL generation and loader to parameterize the data source, increasing flexibility, reliability, and potential download performance by adding an additional distribution point. Commit e99fc7e55ee8990041668ef621255620dd5bd2b4 recorded as 'Parameterize by CDN source; add R2 source support (#544)'. No distinct major bug fixes were required this month; focus was on feature delivery and code quality improvements. Impact: broader data distribution options, improved resilience, and a solid foundation for future multi-source data ingestion, with demonstrated skills in CDN integration, configurability through code refactors, and performance-oriented design.
