Describe a time when you had to work with a team to solve a complex problem.

Situation: Our real-time fraud detection system was dropping events during high-traffic bursts, risking undetected fraud. SRE, Data, and Backend had different views on root cause. Task: Lead a cross-functional resolution and restore system reliability. Action: I led a cross-functional team (SRE, Data, Backend). I facilitated RCA: we identified Kafka consumer lag and a bottleneck in the enrichment layer (N+1 lookups). We implemented auto-scaling for consumers and a caching layer for enrichment data, with load tests to validate. I documented the scaling patterns and ownership model for future incidents. Result: Event loss dropped to near zero; system handled 3x peak load. The playbook was reused for other streaming pipelines. Lesson: Cross-team collaboration and systematic bottleneck analysis are key. Document for scale.
