Hey, This is Vishal Tiwari

Smart Contract Engineer specializing in decentralized systems across EVM and Solana.
I design secure smart contracts, scalable backend services, and full-stack architectures for production-grade Web3 applications.


Focus Areas

  • DeFi protocol design (AMMs, perps, liquidity mechanics)
  • Smart contract development (Solidity, Rust, Anchor)
  • Full-stack dApp engineering (on-chain → backend → frontend)
  • Security, gas optimization, and audit-ready code
  • Distributed systems and event-driven architectures

Experience

Smart Contract Engineer — Black Trade
Designed and audited core trading contracts. Improved protocol security, optimized gas usage, and implemented critical DeFi logic.

Backend Developer — Astrazen
Built scalable APIs, microservices, and Web3 data pipelines for user and protocol workflows.

Full Stack Developer — BndBox
Delivered production dApps with wallet integrations, blockchain event indexing, and real-time UI systems.
