End-to-end delivery
From smart contracts to user interfaces
Modern tech stack
React, TypeScript, Web3 libraries
Polished dApps with intuitive UX, wallet integration, and real-time blockchain data so users have a seamless Web3 experience.
Clear outcomes, the right guardrails, and async updates while we work.
Availability: 1–2 concurrent builds max.
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 responsive Web3 frontends with React, Next.js, and TypeScript. Features include wallet connection (MetaMask, WalletConnect), transaction management, and real-time blockchain data.
Integrated smart contracts with frontend using ethers.js and web3.js. Features include contract interaction, event listening, transaction batching, and error handling.
Developed complete NFT marketplace with minting, buying, selling, and auction features. Includes IPFS integration, metadata management, and royalty distribution.
Implemented support for multiple wallets including MetaMask, WalletConnect, Phantom, and Ledger. Features include wallet detection, connection management, and transaction signing.
Built and deployed subgraphs for efficient blockchain data querying. Features include entity definitions, event handlers, GraphQL queries, and real-time subscriptions.
Founders and operators keeping us honest.
Built our Solana lending protocol—$15M TVL in 3 months.
Shubham built our entire Solana lending protocol from scratch. Anchor programs, risk engine, TypeScript SDK, and admin dashboard. We passed audit on the first try with zero critical findings. The system has been running smoothly for 6 months.
Delivered our DeFi protocol ahead of schedule.
We needed a DeFi protocol built on Ethereum. Shubham delivered it 2 weeks early, and the code quality was excellent. The gas optimizations he implemented saved our users thousands in fees. Highly recommend.
Smart contracts that passed audit on first try.
Shubham wrote our Solana smart contracts. The auditor said it was one of the cleanest codebases they'd seen. We launched to mainnet with confidence. The documentation he provided made it easy for our team to maintain.
I specialize in Solana (Anchor, Rust) and Ethereum (Solidity, Foundry) smart contracts, plus full-stack dApp development with React, TypeScript, and Web3 libraries.
I follow security best practices, write comprehensive tests, use property-based testing, and prepare code for audits. I've maintained a zero critical exploit record over 6 years.
Most Web3 projects take 6-12 weeks depending on complexity. I work in 2-week sprints with weekly demos and transparent progress updates.
Yes, I prepare contracts for audits, work with audit firms, and help respond to findings. I've supported 18+ successful audits.
