Trading Infrastructure Engineer
& Security Researcher

Building production systems where correctness costs money: prediction market bots, on-chain indexers, and low-latency execution layers. $1B+ in on-chain volume across Solana, Polygon, and Hyperliquid.

About

I work at the intersection of blockchain data pipelines, low-latency execution, and production reliability. From prediction markets to Hyperliquid perpetuals to Solana DEXs, I've built the infrastructure behind $1B+ in on-chain trading volume.

I started in security research, discovering vulnerabilities in production systems, writing iOS jailbreak tweaks, and doing responsible disclosure. I carry that first-principles approach into every system I design. When real money is on the line, correctness isn't optional.

FreeRice Network Initiative

2018 20M+ grains donated

Discovered a critical file server misconfiguration in a school district giving student accounts read/write access to all network resources. After responsible disclosure, developed a proof-of-concept: a PowerShell mass-deployment script targeting 5,000+ machines via startup folders, running Python bots that automated FreeRice.com answers. Elevated the school to #1 on the global leaderboard.

Ring Referral Vulnerability

2019 Patched · HackerOne

Discovered a referral spoofing vulnerability in Ring's Neighbors app that allowed unlimited device reward generation. Used Burp Suite and Charles Proxy to intercept and replay network requests, built a Python automation tool demonstrating the exploit at scale. Submitted via HackerOne. Ring acknowledged, patched the vulnerability, and shut down the referral system entirely.
