Achievements / Key results
Blockchain & Smart Contracts- Developed and tested production-oriented Solidity smart contracts using Hardhat, OpenZeppelin, Ethers.js, and EVM-compatible networks. Implemented ERC-20, ERC-721, AccessControl, and compliance-based smart contract functionality. Successfully deployed and tested blockchain applications on VeChain Testnet. GS1 & Supply Chain- Built a GS1 EPCIS 2.0.1 processing pipeline that converts canonical supply-chain data into standardized EPCIS visibility events. Preserved batch genealogy, transformation relationships, process-order relationships, and goods-receipt relationships during event mapping. Implemented domain-based processing across Procurement, Production, and other supply-chain workflows. Blockchain Integrity- Designed a Blockchain Engine connecting EPCIS output with VeChain for batch-level integrity anchoring. Implemented SHA-256 event hashing, Merkle root generation, and dataset-level integrity verification. Kept EPCIS data and sensitive information off-chain, storing only cryptographic integrity anchors on-chain. Testing & Quality- Achieved 79 passing unit tests covering smart contracts, adapters, validation, and integrity functionality. Achieved successful end-to-end testing using real GS1 Engine EPCIS output through the Blockchain Engine. Implemented validation for GS1 identifiers, EPCIS events, CBV mappings, idempotency, and domain partitioning. Web3 & Full-Stack Development- Built decentralized applications using React, Node.js, Express, Solidity, MongoDB, IPFS, Ethers.js, and Web3.js. Developed IPFS integrations supporting file uploads, metadata, multi-file uploads, progress tracking, previews, and gateway access. Delivered complete Web3 workflows from smart contract development → backend integration → frontend integration → testing → testnet deployment.
