During June 2025, LG worked on the hiero-ledger/hiero-local-node repository, delivering a modularized services enablement feature for the Mirror Node Web3 EVM. LG implemented environment-driven feature flags and traffic controls using YAML and env files, updating both .env and docker-compose.yml to support configurable rollouts. This approach allowed teams to toggle the modularized services feature and adjust traffic allocation dynamically, supporting safer, incremental deployments and experimentation across environments. Leveraging configuration management and DevOps skills, LG’s work established a foundation for gradual feature rollouts, though the scope was focused on a single feature without bug fixes, reflecting targeted but limited project depth.
