6 years Web3 experience
Zero critical exploits in production
Audit-ready code
Comprehensive tests and documentation
Production-ready smart contracts with property tests, fuzzers, and formal verification so your protocol is secure from day one.
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 audit-ready smart contracts with comprehensive testing, documentation, and security best practices. Includes Slither analysis, Echidna fuzzing, and formal verification achieving zero critical findings.
Implemented ERC-20, ERC-721, ERC-1155, and custom token standards. Features include minting mechanisms, burning, pausing, access control, and gas optimization.
Built upgradeable contracts using UUPS and Transparent Proxy patterns. Features include safe upgrade procedures, storage layout management, and comprehensive migration testing.
Created production Solana programs with Anchor. Features include custom instructions, PDA architecture, CPI calls, account validation, and optimal compute unit usage.
Built extensive test suites with Foundry and Hardhat. Includes unit tests, integration tests, fuzzing, invariant testing, and gas optimization achieving 100% coverage.
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.
