Featured Project

DeFi Hub

Full-Stack DeFi / EVM Engineering

A self-directed, full-stack DeFi monorepo demonstrating several independent on-chain mechanisms working together: token staking, DAO governance, and a Merkle-tree airdrop system — built with production-grade smart-contract patterns rather than tutorial-level code.

Technical Highlights

UUPS upgradeable smart contracts (StakingPool → StakingPoolV2) via OpenZeppelin Foundry Upgrades
ERC-20 governance token with on-chain, token-based voting (DAO governance)
Merkle-tree token airdrop using merkletreejs and OpenZeppelin MerkleProof
Foundry-based test coverage across all contracts
CEI ordering, reentrancy guards, and least-privilege access control
CREATE2 deterministic deployment with automated address sync to frontend config
Next.js frontend with wagmi/viem wallet integration

TALENT HUNT

Live Demo

GitHub Etherscan

A blockchain-based talent-contest dApp deployed to Sepolia testnet. Users connect a wallet to create, participate in, and vote in contests, with entries and results handled entirely on-chain.

Tools: Solidity Foundry Next.js viem wagmi

Demo Project

VRF Raffle

Live Demo

GitHub Etherscan

A provably fair, on-chain raffle dApp built with Solidity and Foundry, using Chainlink VRF v2.5 for verifiable randomness and trustless draw triggering. The contract handles entry, automated winner selection, and prize distribution, with a live winner feed.

Tools: Solidity Foundry Chainlink VRF Next.js viem

ABOUT ME

I'm a software engineer with 19 years of experience, based in India. I started as a C++ engineer in MNC environments — Wipro, Genpact Headstrong, and Samsung Research Institute — building VoIP phone software, capital-markets applications, and Smart TV browser components.

For the past 11+ years, I've worked as a full-stack web developer, designing, building, and delivering production applications end-to-end — from a multi-tenant recruitment CRM to a WordPress-based touring platform — using React.js, Next.js, Node.js/Adonis.js, PHP, and MySQL.

I'm now applying that engineering background to Web3/EVM development: writing and testing Solidity smart contracts with Foundry, working with OpenZeppelin's upgradeable-contract patterns, and building wallet-connected dApp frontends with viem and wagmi. My Web3 work so far is self-directed, not commercial — and my portfolio reflects that honestly.

I'm currently looking for remote full-stack or Web3 engineering roles.
