Arnab Saha
Engineering Manager
Work
Engineering leader scaling multi-tenant data platforms at enterprise scale. At Atlan, I lead platform engineering for 300+ enterprise customers across AWS, Azure, and GCP.
Key Impact
- 🚀 3x search P99 latency improvement, stabilizing critical enterprise accounts
- 📈 15x metadata throughput, processing 15M+ assets/day at 99.6% success
- 👥 Scaled team from 4 to 10+ engineers while maintaining delivery velocity
- 🛡️ 58% reduction in customer escalations, from reactive fire-drills to predictable ops
- 💰 Daily infrastructure spend reduced by 22%
My team owns the core metadata infrastructure: Apache Atlas on Kubernetes, backed by JanusGraph, Elasticsearch, and Cassandra. I lead an enterprise reliability initiative, Metadata Lakehouse (AI-native data platform), and established an Architecture Review Board for technical governance across the org.
