Hi, I'm Jatin Jain Saraf (JJS)

I am a Senior Software Engineer with 6+ years building high-performance systems end to end — from enterprise B2B supply chains at Kroger and Salesmate CRM to production blockchain infrastructure. I take full ownership of what I build, from schema design to cloud migration.

At Supra Blockchain, I am the lead architect of SupraScan — a native blockchain explorer and indexer for a Move-based chain (similar to Aptos and Sui). The system processes 2,000+ transactions per second with sub-2-second data availability: Kafka pipelines, a distributed Redis locking algorithm coordinating 10+ multithreaded scanner instances, WebSocket pub/sub for real-time delivery, and 80% storage cost reduction ($13K/month) at 20–30 TB.
