Blockchain developer with 3+ years of experience building production-grade DeFi infrastructure, smart contract systems, and on-chain execution tools. I focus on protocol-level development, cross-chain systems, and security-first engineering for real-world financial applications.
Currently working at Lampros Tech, building autonomous DeFi agents and contributing to open-source blockchain tooling. Open to impactful roles in smart contract engineering and protocol development.
- Build end-to-end DeFi protocols: lending markets, liquidity vaults, automated strategies, and execution agents
- Design secure, upgradeable smart contracts with gas optimization and formal verification practices
- Architect on-chain/off-chain systems with caching, indexing, and event-driven automation
- Audit smart contracts, identify vulnerabilities, and implement security improvements
- Contribute to open source and share technical insights through blog posts

DeFi batching platform enabling swap and stake in a single atomic transaction using EIP-5792. Reduced transaction count from 2 to 1, cut gas costs by up to 60%, and improved execution time from 25s to 4s.
Tech: Solidity, Foundry, OpenZeppelin, React, TypeScript, EIP-5792
Automated portfolio rebalancing system on Uniswap with configurable two-token pools, target ratios, and balance thresholds. Built with Foundry and validated across 20+ scenarios with accurate on-chain execution.
Tech: Solidity, Foundry, Next.js, TypeScript, MongoDB, Uniswap
Modular DeFi vault system reusable across EVM chains, improving net yield by 20-40% compared to unmanaged positions. Reduced impermanent loss exposure by 15-30% through active liquidity management and precise share accounting.
Tech: Solidity, Foundry, Node.js, Rootstock, ERC-4626
Security analysis tool for Stylus smart contracts combining static analysis with AI-driven vulnerability detection. Implemented 20+ custom rules using Tree-sitter, improving detection accuracy by 30-40% and reducing manual audit time by 50%.
Tech: Rust, Python, Tree-sitter, OpenAI API, Stylus SDK
Blockchain Developer @ Lampros Tech (Feb 2024 - Present)
Building autonomous DeFi agents with liquidation prevention logic, integrating Uniswap MCP tools for on-chain monitoring, and optimizing backend performance with Redis caching. Contributing to technical content on Uniswap V3/V4, UniswapX, and Interop protocol.
Smart Contract Developer @ Zeru (Feb 2023 - Jan 2024)
Built and shipped an Aave V2-based lending and borrowing protocol that reached $2M+ TVL in production. Designed health factor logic for leveraged strategies, implemented upgradeable contracts using Transparent Proxy pattern, and conducted comprehensive fork-based testing.
