About Me

2021-2023 — Binance

Transaction Auditor

Spent two years watching money disappear onchain by failed deposits, drain patterns, edge cases that nobody planned for. Auditing real transactions at scale taught me exactly how onchain systems fail.

2024 — OKX

Senior Crypto Support

Deepened my understanding of wallet infrastructure, cross-chain behavior, and what happens when users interact with systems that weren't built with them in mind.

2024 — First Smart Contract deployed

Started building in Solidity

Started writing Solidity. Decided to build the systems instead of watching them break.

2025 — Smart Contract Developer

Three protocols, one year

Deployed a Chainlink-integrated raffle, an overcollateralized stablecoin with liquidation logic, and an identity protocol on World Chain mainnet.

2026 — Monad Hackathon

1st place with LockFi

Built a security vault that catches suspicious withdrawals before they execute. Everything I learned watching money get stolen went into this.

Now

Building onchain security infrastructure

Deploying across Ethereum, Monad, World Chain, Stellar. When I'm not coding you'll find me at the beach or playing tennis.
