Worked with popular DeFi protocols like UniSwap, PancakeSwap; NFTs, ERC20, and Governance tokens, Staking, Vesting, and NFT Marketplace Contracts among others. Integrated Hierarchical deterministic wallets to support multi-chain. Integrating Web3 technologies, such as wallets (MetaMask), decentralized identity (DID), or decentralized storage (IPFS), into dApp. Created custom tokens, ICOs (Initial Coin Offerings), and decentralized applications (dApp) using Solidity. Implemented Real-time blockchain data fetching using polygon and etherscan APIs. Enhanced user security using biometric based IDs. Enriched transfer, and managing wallet flows using QR. Created a fixed supply blockchain network. Implemented custom mining algorithms. Designed and developed blockchain workers that dumped all the data from blockchain nodes to persistent DB. Experience with unit testing and test-driven development (TDD) for smart contracts. Integrated web3 to bridge between the blockchain and applications. Utilized various auditing tools and techniques to analyze code, including MythX, Slither, and manual code review. Deployed blockchain nodes on cloud AWS.

Increased transactional transparency by developing a Blockchain-based betting system on BSC Chain, impacting {$5 mln.} in wagers. Developed a Marketplace for smart contracts and DApps. Created a platform/tool for developers to create DApps in minutes by using smart contracts from the marketplace. Configured solidity compiler to compile smart contracts on runtime with different versions. Developed aspects-based feedback system which makes it easy to create custom feedback engagements. Audited the Smart Contracts to make platform more secure and avoid heavy loss. Provided a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents using Elasticsearch. Wrote products documentation and maintaining of documentation for applicable projects. Proficient in Git version control system with a strong command of branching, merging, and collaborative workflows for effective code management.

Built a private blockchain using Hyperledger Fabric 1.0 that enhanced data security and decreased risk exposure by 93%. Successfully integrated three NFT standards (ERC-2535, ERC-721, ERC-1155) into smart contracts, enhancing the platform's interoperability by 20%. Implementation of the ERC standards using Openzeppelin. Developed lottery Decentralized Application using custom lottery contract using randomization algorithm for choosing the winner. Developed ERC721 smart contract where you can buy NFT using ERC20 token. Coded research thesis where IOT firmware is distributed, updated and protected using smart contracts. Reduced the cost by half when airdropping 520 million tokens using bundled address and meta transactions. Wrote a smart contract that is used for airdropping without using owners’ gas by implementing claim function with Merkle Proof. Merkle-Tree-Bulk-Transfer, Multiple-Tokens-Airdrop, Charity-based-NFTS, Lazy minting, platform or developers commission contracts, minting 10,000 NFTs by generating random images based on layers and storing them and their metadata to IPFS. Successful listing of collections on Opensea, Rarible and custom NFTs marketplaces. Integration of paper checkout to buy NFTs from credit card, cryptocurrencies, Google Pay and Apple Pay.
