Worked on stabilizing the mainnet explorer within the blockscout/chainscout repository by addressing a network connectivity and data synchronization issue. The solution involved a targeted deployment and configuration adjustment, rather than direct code changes, which minimized risk and simplified rollback procedures. This approach restored reliable data visibility for users and downstream systems, reducing the likelihood of data gaps in production. All modifications were captured in a single, auditable commit to enhance traceability and change control. The work demonstrated proficiency in deployment management, configuration best practices, and production operations, leveraging skills in Linux server administration and blockchain infrastructure maintenance.
