  • Built personalized cold-email generator; reduced outreach time from 4–5 hours to 90 minutes for 30 emails

  • Kubernetes operations at scale (microservices for 500k+ users) including Helm templating and Azure DevOps CI/CD
  • Production troubleshooting and reliability improvements (tuned HPA; fixed intermittent 503s by adjusting readiness probes)
  • Real-time Kafka pipeline design with idempotency/deduplication and schema evolution handling
