    Resolved a severe N+1 and query-volume problem on a multi-tenant SaaS platform, tracing the bottleneck to an unbounded loop
    over a large collection of active objects; restructured the data access path with eager loading and targeted indexing, cutting
    queries per request from 50–100 down to 5 and response time from 3–5 minutes to under a second.
    • Led the investigation into elevated memory usage across a Resque worker fleet following a major Ruby and Rails 8 stack upgrade:
    instrumented the workers, analyzed allocation and time-series data, ruled out a leak and proved a capacity/headroom root cause,
    eliminating over 100 out-of-memory restarts per day across a fleet of 500 workers.
