Worked on HathorNetwork/hathor-core, delivering nine features and two bug fixes over nine months with a focus on backend reliability, deployment automation, and network scalability. Implemented IPv6 support in P2P networking, enhanced API rate limiting, and improved RocksDB storage management to address disk usage and observability. Developed environment-specific deployment pipelines using Docker, Nginx, and CI/CD workflows, streamlining testnet provisioning and configuration management. Addressed transaction push error handling for clearer user feedback and reduced support overhead. Leveraged Python, TypeScript, and Shell scripting to build robust infrastructure, emphasizing reproducibility, modularity, and maintainability across local, testnet, and production environments.
