I will develop your Web3 dApp with Solidity smart contracts and React frontend

Informazioni su questo servizio
I'm a Full-Stack Web3 Developer with production experience on Celo, Base, Ethereum, and Stacks (Bitcoin L2). I don't just write smart contracts I ship complete, working dApps.
What sets me apart: my own products are live on mainnet right now. CeloSave (DeFi savings, Aave V3), TriviaQ (on-chain rewards game), CeloBank Agent (AI-powered banking agent, ERC-8004 verified), and ChainWarden (B2B compliance API) all built, deployed, and running in production.
I work across the full stack: Solidity smart contracts, React/Next.js frontends, Node.js backends, and deployment infrastructure (Vercel, Railway). I also build AI tooling MCP servers and autonomous agents for projects that need it.
Whether you need a single audited-style contract, a complete dApp with wallet integration, or a full production-ready application with backend and database, I can handle it end to end, in full autonomy.
25+ open source projects, verified mainnet contracts, published npm SDKs all publicly checkable on GitHub (@wkalidev).
Let's build something real. Message me with your project details and I'll get back to you fast.

FAQ
Do you only work with Celo and Base, or other chains too?
I primarily work on Celo, Base, Ethereum, and Stacks (Bitcoin L2), but I'm comfortable with any EVM-compatible chain. Let me know your target network and I'll confirm compatibility before we start.
Can I see your work before ordering?
Yes — check out my portfolio here on Fiverr and my GitHub (@wkalidev), where you'll find 25+ open source projects, including verified mainnet contracts and published npm SDKs.
Do you provide a security audit?
The Standard and Premium packages include a light security review of the code I write. For a full formal audit of an existing complex contract, please contact me first so we can scope it properly.
What do you need from me to get started?
Ideally: your target blockchain network, any existing code or design references, and a short description of what the contract or app should do. If you're not sure yet, message me and we'll figure it out together.
