Joey is a security researcher and builder who specializes in breaking AI models and engineering the systems that power them. With over a decade of software experience and a top-tier global ranking in adversarial research, he bridges the gap between high-stakes red teaming and production-grade development. Currently an AI Security Specialist at Trajectory Labs, pursuing further studies at NAIT.
Conducted comprehensive red teaming on an AI-powered browser extension, identifying critical architectural flaws in system prompt enforcement. Achieved high Attack Success Rates for data exfiltration and credential harvesting via novel conversation history manipulation techniques. Built custom proxy tooling to intercept and analyze API traffic patterns.
Discovered a character encoding vulnerability enabling silent conversation history injection in an AI spreadsheet assistant. Developed universal injection payloads that manipulated sensitive data without user detection and exfiltrated information to external endpoints while the model presented benign output to the user.
Earned 5 accepted bounties for model guardrail jailbreaks, all receiving maximum scores (91-100). Successfully bypassed copyright filters and content safety guardrails across multiple frontier models with consistently high effectiveness ratings.
An adversarial prefix generator that uses gradient-based optimization to bypass LLM prompt guards like Meta's Llama Guard with a >95% success rate.
A popular utility with 15,000+ downloads that converts web applications into native desktop executables by deconstructing PE file formats.
An AI-powered real-time P2P quiz game that uses the Gemini API for dynamic content generation and PeerJS for serverless multiplayer.
Custom firmware for the Raspberry Pi Pico that emulates a Switch Pro controller, enabling remote couch co-op and automation via a Python UART bridge.
A high-performance Linux audio library for virtual node management with per-app routing rules and a Qt6 node-graph editor.
Leading adversarial research and red teaming efforts against frontier AI models.
Migrated a legacy authentication system serving millions of users to Ory. Led team infrastructure and built simulated migration services.
Led Drupal-to-Keycloak auth migration, developed 3 custom Java SSO services. Spearheaded Python 2→3 migration and built ETL tooling.
Managed AWS for 25+ micro-services, optimized Docker builds by 50%, adopted feature flags, merged AWS accounts with zero downtime.
Built real-time phone billing system and call dashboard with Python/Tornado. Slack alerting for high-risk calls.
Cross-platform PySide GUI, serial/wireless device communication, Arduino firmware.
Stock analysis algorithms, Django REST APIs, shipping systems, test tooling, .NET web controls.
