3+ years of blockchain security research experience.

Securing blockchains and smart contracts & AI engineering with https://grego.ai/ ( March 2026 - now ).

Expertise

Solidity smart contracts:

Significant DeFi experience (lending, bridges, staking, DEXes, yield farming ) & understanding of many industry-standard protocols like Uniswap, Morpho, Compound, Aave, Pendle as well as common cross-chain integrations like CCTP, Wormhole or LayerZero.

---

Rust & Go infrastructure:

Several audits of purpose-built L1s and components of L2s like Optimism. I audited Ethereum's Pectra hardfork to deepen my understanding of the EVM and the consensus layer.

---

AI-assisted bug hunting & Judging:

Triaged thousands of complex reports, assessed their validity, impact and likelihood. Submitted multiple valid reports to bug bounty programs.

---

AI enginnering:

Implementing and running benchmarks using my security expertise, researching novel prompt engineering and agentic enginnering solutions, as well as improving the existing pipeline.

Public contests - >$50,000 in rewards total.
