Worked on the sei-protocol/sei-chain repository to enhance reliability and automation for blockchain node operations. Addressed EVM CLI RPC reliability by migrating HTTP requests from GET to POST, updating core RPC helpers in Go to ensure accurate result extraction and stable developer workflows. Improved node identity preservation during state synchronization by backing up and restoring key files, preventing disruptions during upgrades. Automated release publishing using Bash scripting, Docker, and GoReleaser, integrating static binary builds and artifact reproducibility into CI/CD pipelines. Validated these improvements with testing and scripting, reducing manual intervention and supporting safer, more reproducible deployments across diverse environments.
