Developed an internal script that helps system engineers determine the correct action for correctly maintaining Opensearch clusters when unforeseen issues arise, replacing manual investigation through Opensearch dashboards. Beyond the automation itself, led the effort to correctly implement Index State Management (ISM) policies — diagnosing why policy IDs weren't updating, fixing the implementation, and documenting the correct approach for the team.
The tool reduced mean investigation time and brought consistency to the team's triage process across client environments including major enterprises.
What I learned
Opensearch internals and ISM lifecycle, building tools under operational pressure, and how to drive adoption of better practices within an existing team workflow.
