Timeframe: Typical engagement 6–10 weeks.
Collaboration: Weekly demos, shared roadmap, <24h async response.
How we break down the work so you stay unblocked at every phase.
Built a multi-chain DeFi lending protocol with automated market makers, yield farming mechanisms, and cross-chain bridges. Audited smart contracts managing $50M+ TVL across Ethereum and Solana.
Developed a gas-optimized NFT marketplace with dynamic royalties, lazy minting, and on-chain metadata. Includes auction mechanisms and batch operations for reduced gas costs.
Built a decentralized autonomous organization with on-chain voting, proposal systems, and treasury management. Features include quadratic voting, delegation, and timelock mechanisms.
Implemented a Layer 2 rollup solution with optimistic execution and fraud proofs. Achieved 100x gas reduction while maintaining Ethereum security guarantees.
Created complete dApp with React frontend, Solana wallet adapters, and smart contract integration. Features include transaction batching, state caching, and optimistic updates.
Founders and operators keeping us honest.
Would hire again in a heartbeat.
Shubham worked as a contractor on our Web3 project and delivered exceptional results. His code quality, communication, and technical depth make him an ideal team member. He integrated seamlessly with our team.
Senior-level expertise with great collaboration skills.
Shubham joined our team temporarily and immediately started shipping production code. His Web3 expertise and full-stack capabilities made him invaluable. He participated in stand-ups and code reviews like a full-time team member.
Production-ready code from day one.
Shubham joined our Web3 startup and immediately started shipping production code. His Solana and Ethereum experience helped us move fast. The smart contracts he wrote passed audit on the first try.
I specialize in blockchain development, smart contracts (Solidity, Anchor), DeFi protocols, dApp development, and multi-chain integration. I work with Ethereum, Solana, and other blockchain networks.
I offer smart contract development, DeFi protocol engineering, dApp frontend and backend development, security audits, and Web3 consulting. Available for contract and hourly work. Contact me to discuss your Web3 project needs.
I start by understanding your Web3 requirements, then design secure smart contracts and dApp architecture. I focus on security best practices, gas optimization, and production-ready deployments with comprehensive documentation.
I have experience building audited smart contracts and following security best practices. I use tools like Foundry, Hardhat, and conduct thorough testing before deployment. Security is my top priority in Web3 development.
