Led the end-to-end development of a Hyperledger Fabric-based blockchain solution for financial ser- vices, utilizing GoLang for smart contract and backend API development. • DesignedandimplementedRESTfulAPIstointeractwithblockchainsmartcontracts, enablingsecure and scalable loyalty program operations. • Containerized services and chaincode using Docker, orchestrated deployments with Kubernetes, and managed infrastructure as code with Helm charts. • Automated build, test, and deployment pipelines using CI/CD tools to ensure rapid, reliable delivery, and integration of new features. • Collaborated on infrastructure setup, including network configuration, cryptographic assets, and de- ployment scripts for enterprise-grade blockchain environments. • AchievedexpertiseonvariousERCprotocols,includingbutnotlimitedtoERC20,ERC4626,ERC4337, ERC 6960, ERC721, ERC721A & ERC1155. • Performed security research and identified various attack vectors for EVM and SVM based smart contracts. • Developed AI Agents, NFT Price prediction ML model using multiple model stacking. • Designed and implemented liquidity provisions and governance systems in Solana blockchain using Anchor. • Provided Tokenomics advisory and auditing of litepapers for early-stage projects. • Web3 educator for TokenMinds Academy. • Supported ISO/IEC 27001 certification by defining organizational roles and responsibilities (Annex A.6.1) and preparing governance, technical controls, and audit-ready evidence. • Implemented DevSecOps pipelines using GitHub Actions, including SAST automation for Web3 and smart contract codebases. Authored Web3 Secure Development Guidelines, covering smart contract security, CI/CD hardening, key management, and threat modeling. • Designed Business Continuity & Disaster Recovery (BC/DR) artifacts aligned with ISO 27001 Annex A.17, including runbooks, recovery workflows, and incident scenarios

Audited StarkGate, the bridge between the Ethereum network and Starkware using Echidna. • Contributed in finding 3 Best Practices issues in the RookFi Swap contract, which accounted for 27.28% of total best practice findings. Cryptography Research • Collaborated with Aural Research group to implement a zkSNARK verifier smart contract using whose proof size is lower than any other other zkSNARK. • Checked gas usage by Marlin protocol on a polynomial of 216 Degrees, to compare with Vampire protocol using ZoKrates. • Studied the precompile operations of elliptic curves. • Worked on making efficient multiplication over bn254 or bls12-381.
