Currently: Evolving SupraScan multi-VM architecture for Supra testnet

Hi, I'm Jatin Jain Saraf (JJS)

I make PostgreSQL work at production scale.

I'm the architect of SupraScan, Supra Blockchain's native explorer and indexer. It indexes 500–1,000 transactions per second with sub-2-second data availability, on a PostgreSQL database that grew to 10 TB before I cut it to 2.7 TB. That storage work, from schema redesign and partitioning to TOAST optimization and table repacking, cut storage costs by 80% ($30K/month).

Senior Software Engineer, distributed systems, databases and infrastructure. 6+ years building high-performance systems end to end, from enterprise B2B at Kroger and Salesmate CRM to production blockchain infrastructure. I own what I build, from schema design to cloud migration.
