About Me
I'm Henry Sharafzad, a Blockchain Developer and Smart Contract Engineer based in London, UK, with 2+ years of production experience shipping real systems across Ethereum, Solana, and EVM L2 networks.
I've built DeFi protocols integrating Uniswap V3, full dApps with DAO governance and milestone escrow, encrypted messaging platforms on XMTP, and multi-provider AI agent systems, all deployed to production with real users.
My MSc research (Distinction) focused on Zero-Knowledge Proofs and Solana Cross-Program Invocations, combining privacy-preserving cryptography with on-chain composability for a connected vehicle trust network.
Smart Contracts & DeFi
Solidity, Rust/Anchor on Solana, Uniswap V3 AMM integration, DAO governance, factory & vault patterns across 8 production chains.
AI & LLM Systems
Multi-provider LLM platforms (OpenAI, Anthropic, Gemini, XAI), agentic decision loops, RAG pipelines, and production NLP at scale.
Full-Stack Engineering
Next.js, FastAPI, Node.js microservices, Redis pub/sub real-time engines, PostgreSQL at production scale.
Research & ZKPs
Original MSc research: Groth16 ZKP circuits, Solana CPI composable architecture, Bayesian anomaly detection · 100% detection precision.
