You will get a Custom Web3 DApp with smart contracts & blockchain backend
Project details
Looking to launch a secure, scalable DApp on Ethereum, Polygon, or BNB Chain? You're in the right place.
I develop full-stack decentralized applications that combine clean frontend interfaces with secure, gas-optimized smart contracts. Whether you're building an NFT marketplace, DAO, staking platform, DeFi protocol, or token launchpad, I offer a complete solution tailored to your blockchain goals.
🔧 What I offer:
-Custom Web3 DApps using React, Next.js, Web3.js, or Ethers.js
-Smart contract development in Solidity (ERC20, BEP20, NFT, vesting, staking, etc.)
-Wallet integrations (MetaMask, WalletConnect, Coinbase Wallet)
-Secure contract deployment on Ethereum, BSC, Polygon, or other EVM-compatible chains
-Full testing and optimization using Hardhat or Truffle
-Decentralized backend support via Moralis, The Graph, IPFS/Pinata, and Alchemy
-Bonus: Automation support with Make.com, Zapier, or Latenode( where needed)
Expect clear updates, production-ready code, and post-launch support. Let's build your Web3 vision together: message me to get started today.

About Joshua
Expert Web3 DApp & Smart Contract Developer | Helping Startups Build
Ilorin, Nigeria - 4:45 pm local time
💡 I’m a perfect fit for clients who:
-Are launching an NFT, DeFi, or Web3 SaaS product and need an experienced full-stack blockchain developer to lead from idea to launch.
-Want secure, gas-efficient smart contracts with custom logic, clean architecture, and comprehensive test coverage.
-Are non-technical founders who need a trusted technical partner—someone who communicates clearly and can translate business needs into smart contract logic.
- Have tight deadlines or investor pressure and want to avoid common pitfalls in Web3 dev—no hacks, no delays, no sloppy code.
-Want to cut dev time and costs by working with someone who can handle Solidity, smart contracts, frontend, and backend without needing to hire multiple devs.
🔍The Real Struggles Most Founders Face in Web3:
You've got a brilliant idea but you’re overwhelmed by the complexity of launching a secure and scalable DApp. Maybe your last developer left spaghetti code with vulnerabilities. Or you’re worried about costly exploits, high gas fees, or not knowing if your smart contracts will work under pressure.
Many founders delay launch due to technical issues, run into hidden gas costs, or worse—deploy unsafe contracts without audits. It’s frustrating, risky, and expensive.
⚙️ How I Help You Win:
With 3+ years in the blockchain space and 6+ years in the software engineering industry building real-world projects across DeFi, NFT marketplaces, DAOs, and launchpads, I provide end-to-end development and technical strategy, not just code.
Here's what you'll get working with me:
✅ Gas-optimized Solidity smart contracts that save 15% – 40% on deployment and interaction costs
✅ Scalable full-stack Web3 DApps built with React or React native, Node.js, and EVM-compatible contracts
✅ Scripts for token launches, liquidity pools, staking, airdrops, NFT drops, and more
✅ Custom cross-chain logic for Ethereum, BSC, Polygon, and other chains
✅ Thorough testing (Hardhat, Foundry) to prevent exploits and edge-case failures
✅ Full transparency and guidance and no jargon, just results
> Clients who work with me typically reduce development time by 35%, save 15% – 40% in gas fees, and eliminate 90% of security risks through thorough audits and test coverage.

🚫 Not the right fit if you:
- Want to copy/paste code from Fiverr or GitHub repos
- Don’t have a clear product goal or aren’t serious about launching
- Expect 24/7 response without a scope or timeline
- Are not open to feedback or best-practice guidance
