Blockchain,Web3 and Ai Development for Startups and BusinessMd Sabbir Hossain
I help startups and businesses build secure, scalable blockchain and Web3 applications from concept to deployment.
With experience in smart contracts, blockchain infrastructure, and full-stack engineering, I turn complex ideas into practical, production-focused Web3 products.
What I can build
Smart contracts and token standards (ERC-20, ERC-721, ERC-1155)
Decentralized applications (dApps)
DeFi applications and wallet integrations
Real-world asset (RWA) tokenization platforms
Web3 dashboards, APIs, and backend systems
Private and enterprise blockchain solutions
Blockchain explorers, indexing, and transaction integrations
Cross-chain and Layer 2 integrations
My development approach
Define requirements and technical architecture.
Build smart contracts and application components.
Integrate wallets, APIs, and blockchain networks.
Test, deploy, and document the solution.
I work with Solidity, Ethereum-compatible networks, React, Next.js, Node.js, and enterprise blockchain technologies, selecting the right stack for each project.
Why work with me?
Direct communication with your developer
Architecture designed around your business goals
Transparent milestones and technical documentation
Focus on maintainability, security practices, and scalability
Have a Web3 idea, an existing dApp to improve, or an RWA platform to build?
Let's discuss your requirements and turn your vision into a working product. Smart contract development does not replace an independent security audit.
