Key Responsibilities

Platform Performance & Optimization Profile backend, database, and API performance; find bottlenecks before users feel them. Reduce p95 latency site-wide.

Scalability Architecture Evaluate and re-architect components to sustain 100× current peak load. Lead decisions on horizontal scaling, autoscaling tuning, and monolith-vs-service boundaries as the system matures. Own infrastructure-as-code and the deployment pipeline.

Reliability & Uptime Own SLAs/SLOs for latency, throughput, and availability, targeting a 99.9% uptime SLA. Design HA database + disaster recovery, set tight alerting thresholds, and keep on-call lightweight and predictable. Keep the platform stable through growth spikes, ad campaigns, and influencer pushes.
