About this Gig
Are you looking to automate blockchain workflows, build a custom DApp, or deploy a reliable Web3 script?
As a developer with over 5 years of experience in Python and JavaScript, I turn complex blockchain concepts into secure, functional realities. Whether you need to interact with Ethereum, Polygon, Base, Arbitrum, or BSC, I write clean, production-ready code tailored to your requirements.
What I Offer:
- Web3 Automation & Bots: Custom scripts for wallet tracking, event listening, automated liquidity, and trading bots.
- Smart Contract Interaction: Seamless integration with protocols using Web3.py or Ethers.js to read/write data and decode transactions.
- Full-Stack DApp Development: Responsive frontends using React and Next.js, integrated with MetaMask, WalletConnect, and RainbowKit.
- Backend & Custom APIs: Node.js or Python (FastAPI) backends to cache blockchain data and prevent rate-limiting.
- DeFi & NFT Integrations: Custom tools for Uniswap forks, flash loans, and automated minting.
Why Work With Me?
I write gas-optimized, secure code to save on transaction fees. Every project includes clear setup documentation so you can run the scripts without technical headaches.
