Security first
Best practices and audits
Multi-chain
Ethereum and Solana expertise
Secure smart contract development with comprehensive testing, audits, and production deployment.
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.
Developed custom ERC-20 tokens with advanced tokenomics including vesting schedules, fee mechanisms, and anti-whale protection. Fully audited and deployed on mainnet.
Implemented proxy patterns for upgradeable contracts using UUPS and Transparent Proxy patterns. Includes comprehensive testing and safe upgrade procedures.
Built extensive test suites with Foundry and Hardhat including unit tests, integration tests, fuzzing, and formal verification. 100% code coverage with edge case handling.
Created production-ready Solana programs with Anchor framework. Includes PDA design, CPI calls, account validation, and efficient state management.
Conducted security audits identifying vulnerabilities including reentrancy, access control issues, and economic exploits. Provided detailed reports and remediation guidance.
Founders and operators keeping us honest.
Would hire again in a heartbeat.

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.
