Sobre este Serviço
Need a blockchain developer who does more than just deploy contracts? I help startups, founders, and businesses build secure, production ready Web3 products that generate real value from token launches to full DApps.
With 3+ years of experience, I build smart contracts, NFT platforms, DeFi protocols, and Web3 apps using Solidity, ethers.js, Flutter, and React Native. I work on token launches, NFT collections, staking systems, DAO governance, and AI-powered Web3 mobile apps.
My focus is not just coding. I help you build a product that is secure, scalable, and aligned with your business goals.
What you can expect:
- Smart contracts ERC-20, ERC-721, ERC-1155, custom logic
- DApps with MetaMask and WalletConnect integration
- NFT platforms, DeFi protocols, and DAO systems
- Multi-chain deployment Ethereum, BNB, Polygon, Arbitrum
- Security review and on-chain verification included
- Gas optimization and clean, documented code
- Web3 mobile apps for iOS and Android
- Full source code ownership on delivery
Click 'Request to Order' and let's bring your Web3 product to life!

Perguntas frequentes
Which blockchains do you develop on?
I work on all major EVM-compatible chains including Ethereum, BNB Chain, Polygon, and Arbitrum. I also support Base and Avalanche on request. If you have a specific chain in mind that is not listed, send me a message and I will confirm before you order.
Do I need to know anything about blockchain to work with you?
Not at all. Many of my clients come with a business idea and no technical background. I translate your goals into the right technical solution, explain things in plain language, and guide you through every decision so you always know what is being built and why.
Will I own the smart contract and source code after delivery?
Yes, 100%. Full ownership of all source code, contracts, and documentation is transferred to you upon delivery. No licensing fees, no ongoing dependencies on me unless you choose to continue working together.
Will my smart contract be verified on a block explorer?
Yes. On-chain verification on Etherscan, BscScan, or Polygonscan is included in every package. Verified contracts build trust with your users and investors, so this is a baseline for every delivery, not an add-on.
Can you build a mobile app alongside the blockchain product?
Yes, and this is one of my strongest differentiators. I build native iOS and Android apps using Swift and Flutter, so I can deliver a complete Web3 product,smart contracts, backend, and mobile app, all in one engagement. This is available under the Premium package.
What information do you need to get started?
A brief description of what you want to build, which blockchain you prefer, your target launch date, and any reference projects or documents you already have. The more context you share upfront, the faster we can align on scope and begin.
