About this Gig
Looking to launch a secure Web3 project or build a custom decentralized application? Look no further!
I'm Rayyan a dedicated blockchain developer, I engineer secure, gas optimized Solidity smart contracts and build full stack dApps for Ethereum, Binance Smart Chain (BSC), Polygon, Base, and all major EVM networks.
Whether you need a token launch, an NFT minting platform, or a complex DeFi protocol, I deliver clean, production ready architecture tailored to your exact business logic.
I prioritize test driven development (using Hardhat) to simulate edge cases and validate your code on testnets before mainnet deployment.
My Services Include:
- Custom Solidity smart contracts (ERC-20, ERC-721, ERC-1155, custom utility tokens)
- Full stack dApp front-end & back-end integration (React, Next.js, Web3.js, Ethers.js)
- Automated smart contract unit testing & gas optimization
- Staking, vesting, and yield farming dApps
- Custom NFT minting engines & Web3 dashboards
- Token presale contracts, launchpads, and governance DAOs

FAQ
What do you need from me before starting my project?
Simply send me a message with your project idea or feature requirements. If you don't have a formal technical specification ready, don't worry we can discuss your vision and map out the full architecture together before starting.
Do you test the smart contracts before mainnet deployment?
Yes, absolutely! I prioritize test driven development using Hardhat to write automated unit test suites. We thoroughly test gas efficiency, edge cases, and core logic on a testnet before any smart contract goes live on mainnet.
Which blockchain networks do you build dApps for?
As a dedicated blockchain developer, I write EVM compatible Solidity smart contracts and build dApps for Ethereum, Binance Smart Chain (BSC), Polygon, Base, Arbitrum, Optimism, and Avalanche.
Will I receive 100% ownership of the source code?
Yes. Upon order completion, you receive 100% code ownership and full access to the complete source code repository for both the smart contract backend and the dApp front end.
What happens if I encounter an issue after delivery?
Every order includes 14 days of free post launch support. If any bug or technical issue arises within the agreed-upon project scope, I will patch and resolve it immediately at no additional cost.
