Vishal Kumar
Software Engineer Platform & Infrastructure
I build platform infrastructure and distributed systems. At Atlan, I migrated 600+ production tenants to CloudNativePG with zero data loss, built Blackbird (a declarative config system managing 800-1000 tenant clusters), and productionized the Temporal workflow engine. I use Claude Code heavily as a daily driver, which compresses 2-3 months of engineering work into 2 weeks, routinely.
Active in Google Developer Groups (Bangalore, Kolkata, Durgapur) and the K8s Bangalore community.
