Project details
I build secure, scalable DeFi protocols including staking, yield farming, lending & borrowing, & liquidity pools. From smart contracts to deployment and testing, I deliver production-ready DeFi systems designed for real users and real liquidity. I provide end-to-end DeFi protocol development, helping Web3 startups & blockchain projects launch reliable, secure, & scalable decentralized finance products.
DeFi Services:
DeFi Smart Contract Development: ERC20 / BEP20 token integration, modular & upgradeable contract architecture, gas-optimized code, role-based access control.
Staking & Yield Farming: Fixed and flexible staking pools, reward distribution logic, custom APR/APY calculation, lock-up and penalty mechanisms.
Lending & Borrowing Protocols: Supply and borrow pools, custom interest rate models, collateral & liquidation logic, decentralized oracle integration.
Liquidity Pool & AMM: Liquidity pool creation, swap and fee mechanisms, LP token logic, DEX integration.
Why Work With Me:
Practical DeFi with clean, readable, and highly scalable code.
Heavy focus on financial safety and smart contract optimization.
I don’t just write smart contracts — I build functional DeFi systems.

Custom DEX DApp Developer for IGC
Hired him to build a full DEX (IGC) from scratch including smart contracts, liquidity setup, swap system, and deployment. He delivered a fully working Web3 product with solid architecture and smooth functionality.
Strong technical skills in blockchain development and able to handle complex DEX logic with minimal supervision. Communication was clear and consistent throughout.

DApp Integration Expert Needed for Wallet Login and Backend Setup
He helped us finish the integration part of our DApp and everything worked as expected. Wallet login was set up correctly and the frontend was connected to the contracts without problems.
He was responsive, easy to communicate with, and understood what needed to be done without too much back and forth. Happy with the result.

Smart Contract Developer Needed (ERC-721 / ERC-1155 Only)
Good experience overall. He understood the requirement quickly and delivered the smart contract as requested. The code was clean and easy to follow, and he made a small adjustment after delivery without any issue.

I don’t just write code. I build and modify real, live blockchain systems that are meant to go to mainnet, scale, and generate usage.
If you need someone who only delivers “MVP demos,” I’m probably not your guy.
But if you need someone who can take your project from idea to testnet, then mainnet deployment, and into a working, user-ready product — then we should talk.
What I Do (End-to-End Web3 Execution):
• Smart Contract Development & Mainnet Deployment
• Production-Ready DApps & Backend Infrastructure
• Token Launches (ICO / IDO / Presale)
• Wallet Integration & Payment Infrastructure
• Liquidity, Volume & Growth Strategy
• Cross-Chain & Dual-Chain Systems
• Security-Focused Web3 Infrastructure
Blockchain & Web3 Development:
As a Full-Stack Blockchain Developer, I build scalable, audit-ready, and production-grade systems across Ethereum, Solana, BSC, Polygon, Arbitrum, and EVM ecosystems.
Smart Contracts (Solidity / Rust):
• ERC-20 / ERC-721 / ERC-1155 / SPL Tokens
• Token deployment on Ethereum & Solana
• Staking, vesting, minting & governance systems
• Smart contract testing, debugging & audit-ready delivery
• Gas optimization & security-first engineering
• Etherscan verification & production deployment
DApp Development (Full-Stack Web3):
• React.js / Next.js frontend + Node.js backend
• Web3.js / Ethers.js integration
• Wallet integrations (MetaMask, WalletConnect, Phantom)
• APIs, dashboards & admin panels
• Backend infrastructure & automation systems
• Production infrastructure deployment & go-live execution
