About Me

Smart-contract engineer building DeFi protocols end-to-end. Shipped a token-pool prize DApp to BSC mainnet (live, verified, with real on-chain user activity). Currently building a Uniswap V2-style AMM from scratch in Foundry, applying production-grade patterns (CEI ordering, MINIMUM_LIQUIDITY lock, slippage protection). Strong full-stack Web3: Solidity, Foundry, frontend integration, tokenomics, mainnet deployment.

Working at Cognizant by day, building toward smart-contract security and protocol engineering by night.

Featured Projects

0xProfit

Live Demo · BSCscan

Pool-Based Prize DApp on BSC Mainnet (April 2025)

  • Designed and shipped a TokenPool smart contract handling timed prize pools across 5/10/15-token pool tiers with custom ERC-20 token (0xP) integration.
  • Built the complete stack solo: Solidity 0.8.26 contract, Web3 frontend with wallet integration, deployment scripts, and whitepaper.
  • Verified source on BSCscan with end-to-end on-chain activity from multiple real wallets.
  • Engineering lessons internalized: Block-data randomness exploitability (would use Chainlink VRF in v2), strict CEI ordering, and owner-privilege scope design.

Mini-AMM

GitHub Repo

Uniswap V2-Style DEX (In Progress, 2026)

  • Building a constant-product AMM from scratch in Foundry — implementing pool logic, LP token math, swap math, and slippage protection.
  • Implemented addLiquidity with first-LP geometric mean (sqrt(x·y)) and subsequent-LP formulas.
  • Applied production patterns: CEI ordering, MINIMUM_LIQUIDITY = 1000 lock against first-LP inflation attacks, zero-amount input validation.
  • Target: mainnet deployment on Base with a wallet-connected frontend.

CrowdFunding-Factory

Live App · GitHub Repo

Trustless Crowdfunding DApp (Sepolia, 2025)

  • Trustless platform using the Factory pattern — spawning isolated Campaign contracts per fundraise.
  • Deployed to Sepolia testnet with verified frontend, Foundry test coverage, and live Netlify integration.

ERC-20 Token Suite

GitHub Repo

Base Assets for AMM Integration (Sepolia, 2025)

  • Built OpenZeppelin-based ERC-20 token contracts. Deployed and verified on Sepolia testnet.
  • Used cast wallet import for secure private-key management (no .env keys).
