May 2025: Delivered two core features across celestia-app and celestia-core, with strong test coverage and storage optimization improvements. TxClient: Concurrent Multi-Endpoint Broadcast enables broadcasting to up to three gRPC endpoints, returning the first successful response; tests added. Blockstore/State Store Directory Separation enables placing blockstore in a separate directory via a new config option; initialization logic updated; documentation and tests included. Impact: higher transaction throughput, more flexible deployment/topology, and optimized storage I/O. Technologies: Go, concurrency patterns, gRPC, config-driven design, testing, documentation. Business value: improved performance, resilience, and deployment flexibility.

April 2025 monthly summary for celestia-app: Delivered robust Makefile improvements to the BBR enable/disable workflow, adding conditional execution, explicit command-status checks, and finalization logic so success messages are only shown after all steps complete. This reduces misleading CI output and lowers deployment risk by ensuring reliable BBR toggling in build and test pipelines. The change was implemented in celestiaorg/celestia-app (commit a75d1f88a95690105e0cfd2d0748610dd0300c13; 'chore: check command status in BBR enable/disable targets (#4582)').
