Blockchain Protocol Engineer (EVM & Solana)

TL;DR: I build production-grade blockchain systems across EVM and Solana, from protocol primitives to control planes, automation, and security-aware infrastructure.

I design and ship end-to-end blockchain systems that combine protocol logic, execution infrastructure, and operational control layers.

• protocol primitives and smart contracts
• Solana programs with Anchor and Rust
• account abstraction and smart-account flows
• staking, stablecoin, and DeFi systems
• control planes for monitoring and operations
• automation pipelines and agent-driven execution

• 🔗 Protocol Engineering — smart contracts, Solana programs, staking, account abstraction (EIP-4337), composability
• ⚙️ On-chain Systems — invariants, failure modes, economic design, protocol architecture
• 🤖 Automation & Agents — bots, scripts, autonomous agents, on-chain / off-chain workflows
• 🧩 Control Planes — APIs + dashboards to operate and validate on-chain systems
• 🛡 Security-first Design — honeypots, exploit modeling, defensive smart contract patterns

Languages: Solidity • Rust • TypeScript • JavaScript • Python
Chains: EVM • Solana
Tooling: Foundry • Hardhat • Anchor • Docker • Linux • GitHub Actions
Control Plane UI: React • Next.js
