ENGINEERING
MINDSET

I build secure and scalable blockchain systems across EVM and Cosmos ecosystems. From designing Solidity smart contracts and testing complex protocol logic to developing Cosmos SDK–based chains, I treat security, correctness, and decentralization as fundamental requirements.

My work spans the full blockchain development lifecycle: smart contract engineering in Solidity, advanced testing with Foundry and Echidna, protocol security reviews, and blockchain infrastructure development in Go. I operate at the intersection of protocol design, security research, and production-grade blockchain engineering.

Currently focused on smart contract security, cross-chain protocols, and next-generation decentralized infrastructure.

SECURITY-FIRST

Security is a fundamental design principle. I focus on smart contract correctness through manual reviews, adversarial thinking, comprehensive testing, and advanced fuzzing methodologies.

PERFORMANCE ENGINEERING

Developing decentralized systems across EVM and Cosmos ecosystems, with experience in Solidity, Foundry, Echidna, and Go-based blockchain development.

INTEROPERABILITY

Exploring and building interoperable blockchain infrastructure, focusing on secure communication, asset settlement, and next-generation decentralized protocols.

FINDINGS

Virtuals Protocol

Virtuals Protocol

SherlockHIGH

▸ROOT CAUSE

PublicContributionNft::mint was publicly callable with no access control, allowing any address to invoke it.

▸IMPACT

Attackers could mint arbitrary NFTs and manipulate contribution accounting, resulting in cascading fund loss throughout the protocol.

Silo Finance

Sherlock

Silo Finance

SherlockMEDIUM

▸ROOT CAUSE

deposit(), withdraw(), and redeem() lacked slippage protection and deadline validation parameters.

▸IMPACT

Users exposed to sandwich attacks and stale transaction execution at unfavorable prices.

Liquid Ron

Liquid Ron

SherlockMEDIUM

▸ROOT CAUSE

Incorrect onlyOperator authorization logic used the wrong address for role comparison.

▸IMPACT

Authorized operators permanently blocked from executing critical protocol functionality, causing denial-of-service.

Aegis.im YUSD

Cantina

Aegis.im YUSD

CantinaMEDIUM

▸ROOT CAUSE

Shared asset accounting allowed multiple positions to draw against identical collateral simultaneously.

▸IMPACT

Protocol insolvency through undercollateralization — bad debt accumulates silently with no liquidation trigger.

Jigsaw Protocol

Cantina

Jigsaw Protocol

CantinaMEDIUM

▸ROOT CAUSE

Missing health-factor checks during repayment flow allowed positions to skip mandatory solvency validation.

▸IMPACT

Undercollateralized positions became permanently non-liquidatable, locking protocol bad debt with no recovery path.
