Summary
🤩
Rockstar🎓
Top SchoolSayli Patil is a founder and seasoned software engineer with 9 years of experience building backend systems, now based in Dubai and focused on making payments cheaper for everyday businesses. She previously led technical teams at The Dapp List and contributed core backend features to Polygon (Matic) projects, including validator node refactors and deposit/state-sync implementations for a major blockchain platform. Her hands-on work spans JavaScript libraries and Go-based blockchain clients, with notable contributions to withdrawals, Merkle proofs, and streamlining bank-related modules in high-profile open-source repos. As a founder at Cray, she combines product intuition with deep engineering experience to tackle payment frictions that retailers face. She holds an MCA in Computer Science and brings a pragmatic, security-minded approach to distributed systems and payment flows. A detail not obvious from titles alone: her open-source commits show she prefers surgical refactors that simplify state management and remove fragile functionality rather than piling on features.
