Auditor Profile

About

I am a smart contract security researcher with a strong focus on Solana / SVM Rust, Cairo / Starknet, and complex DeFi protocol security.

My core expertise is reviewing systems where correctness depends on protocol-specific logic rather than standard contract patterns. I have extensive experience with Solana programs, Rust-based blockchain code, Cairo/Starknet systems, AMMs, vaults, staking and rewards logic, governance systems, bridges, orderbooks, launchpads, smart wallets, and other DeFi protocols with non-trivial accounting and state transitions.

I have 5+ years of smart contract security experience, after studying Information Security / Cybersecurity and working as a penetration tester. In private audits, I have completed 38 Solana / Rust engagements totaling 197.5 audit days, including repeated work on Meteora, Jupiter, GMX Solana, Paladin, Ondo, Orderly, 1inch Solana, Ergonia, Dripster, Blendy, Token Mill, Bridge, Autonomous Finance, and other SVM / Rust protocols.

I am also highly experienced in Cairo / Starknet security, with 6 private Cairo audits totaling 67 audit days, including Ekubo, Vesu, Forge, Starknet Foundation Alexandria, and Starkware Cairo. My Cairo work includes AMM logic, Cairo libraries, Starknet protocol code, storage and serialization behavior, math-heavy code, and invariant-driven protocol review.

Across public contests, I have won six security contests, achieved four top-three placements, and placed top-10 four additional times. My Rust and non-EVM record includes 1st in Grass for Rust / Solana, 6th in Tensor for Rust / Solana, 7th in Solayer, 1st in Centrifuge for Rust / Substrate, 1st in HydraDx for Rust / Substrate, and 3rd in Andromeda for Rust / Cosmos.

I currently work as a Security Researcher with Spearbit, Zenith, and Blackthorn, and I also compete in contests on Code4rena, Cantina, and other audit platforms.

Core Expertise

Solana / SVM Rust

Solana / Rust is one of my strongest areas. I have reviewed a large number of production Solana protocols across AMMs, smart wallets, launchpads, vaults, bridges, staking systems, governance systems, payments, and token/accounting logic.

My Solana review work focuses on account validation, authority and signer checks, PDA derivation, initialization and reinitialization safety, CPI assumptions, token-account validation, protocol accounting, arithmetic precision, invariant preservation, and edge cases around user-controlled accounts and program state.

Representative Solana / Rust work includes Meteora, Jupiter, GMX Solana, Paladin, Ondo, Orderly, 1inch Solana, Ergonia, Dripster, Ego, Token Mill, Blendy, Bridge, Autonomous Finance, and multiple Accretion engagements.

Cairo / Starknet

I have strong Cairo / Starknet experience from both protocol and library audits. I have reviewed Cairo AMMs, Starknet protocol code, Cairo libraries, math-heavy components, storage and serialization behavior, and state-transition logic where small implementation errors can lead to broken accounting or invalid system states.

Representative Cairo / Starknet work includes Ekubo, Vesu, Forge, Starknet Foundation Alexandria, and Starkware Cairo.

DeFi Protocol Security

I have broad DeFi audit experience across AMMs, concentrated liquidity, bonding curves, orderbooks, vaults, staking, rewards, governance, lending, cross-chain systems, payment flows, and token standards.

My strongest reviews are usually on systems where the important bugs are not isolated to one function, but emerge from the interaction between accounting rules, user flows, state transitions, access control, and economic assumptions.

Rust-Based Blockchain Systems

Beyond Solana and Cairo, I have strong experience with Rust-based blockchain systems, including Rust / Substrate, Rust / Cosmos, and Rust backend protocol components. My public contest record includes first-place Rust/Substrate results and a top-three Rust/Cosmos result.

Solidity / EVM

Solidity / EVM remains a strong secondary area. I have audited and competed across ERC standards, lending, governance, staking, proxies, Gnosis Safe integrations, cross-chain protocols, and DeFi systems. My main edge in EVM work is on complex protocol logic rather than generic token or admin patterns.
