I am Lingraj Mahanand, a Blockchain Architect & Consultant specializing in enterprise FinTech infrastructure, blockchain-enabled backends, and regulated trade finance ecosystems. Over the past 15+ years, I have designed and delivered scalable platforms for global banks and fintechs, focusing on Solidity/EVM contracts, NodeJS/TypeScript backends, tokenization of real-world assets, and compliant digital trade workflows. I lead architecture and delivery initiatives, building gasless signing flows, relayer patterns, EIP-712 signing, and zk-proof integration for privacy-preserving verification. I collaborate with banks, regulators, and ecosystem partners to architect interoperable electronic trade document workflows (eBL, ePN, Bills of Exchange) and digital asset infrastructure across tradable assets and finance use cases.…I am Lingraj Mahanand, a Blockchain Architect & Consultant specializing in enterprise FinTech infrastructure, blockchain-enabled backends, and regulated trade finance ecosystems.
