Hi, I’m Jatin Jain Saraf
I am a builder driven by the challenge of transforming complex requirements into high-performance systems, bringing nearly 6 years of experience that spans the evolution of enterprise B2B supply chains to the cutting edge of Web3 infrastructure.
Currently, at CodeZeros/Supra, I drive the core development of SupraScan, the native explorer and high-performance indexing system for the Supra Blockchain. My work involves architecting low-latency data pipelines to synchronize live blockchain data across a sophisticated multi-VM environment (MoveVM and EVM).
Check live work: SupraScan.io
My specialized expertise includes end-to-end integration of Starkey (Supra’s native wallet). I have a proven track record of modernizing enterprise ecosystems, including migrations to Node.js 22 and Next.js 16, while previously leading core modules for Kroger (TOQ) and Salesmate CRM.
