Signal Stats Pipeline Performance

Pre-Aggregator Design: Identified an Apache Storm execution bottleneck in the real-time statistics pipeline. Built a high-performance Python pre-aggregator to pull messages from Kafka and batch-aggregate counts before flushing, achieving a 50x efficiency improvement.
Modern Telemetry Stack: Spearheaded the migration from an outdated sinatra/scribed logging pipeline to a distributed architecture using Suro, Kafka, Storm, and KairosDB to support global, business-critical tracking metrics.
Database Tuning: Upgraded the core MySQL Galera and MongoDB replica sets, optimization of queries which slashed web UI latency by 20x.
