Blockchain Developer,Solidity| DeFi Flash Loan| Crypto Bot| Solana MEV
I build production-grade blockchain systems that move fast and execute precisely flash loan arbitrage contracts, MEV bots, on-chain DeFi protocols, and automated trading infrastructure across Ethereum and Solana. With deep expertise in Solidity and the Solana ecosystem, I work directly with DeFi protocols including Aave, Uniswap V3, Curve, Balancer, and Jupiter integrating flash loans, swap routing, liquidity management, and MEV extraction into auditable, gas-optimised smart contracts. What I Build ▸ Flash Loan Arbitrage Systems Multi-hop arbitrage contracts using Aave V3 / Balancer flash loans, routed through Uniswap V3, Curve, and Sushiswap. Atomic execution with on-chain profit validation before every transaction. ▸ MEV & Trading Bots (Solana + EVM) Jito-based Solana MEV bots, sandwich detection, backrunning strategies, and Ethereum mempool monitoring bots built with Ethers.js and web3.py. ▸ DeFi Protocol Development Custom AMMs, yield aggregators, staking contracts, token launchpads, vesting schedules and DAO governance fully tested with Hardhat and Foundry. ▸ Smart Contract Auditing & Optimization Gas profiling, reentrancy protection, access control review, and vulnerability assessments for existing Solidity codebases. Tech Stack Solidity · Rust · TypeScript · Python Ethers.js · Web3.js · Anchor Framework Hardhat · Foundry · Truffle Aave V3 · Uniswap V3 · Curve · Balancer · Jupiter · Raydium Chainlink · The Graph · IPFS Node.js · PostgreSQL · Redis Why Clients Choose Me ✔ I write clean, auditable code not copy-paste scripts ✔ I communicate clearly and hit deadlines ✔ Every contract ships with tests and documentation ✔ I understand both the code and the financial logic behind DeFi Whether you need a flash loan bot deployed at anytime or a full DeFi protocol Built from the ground up, let's talk about what you're building.
