A CTF-style playground with 7 progressively harder prompt injection challenges. Each level adds new defenses, from naive prompts to input analysis, output filtering, and a two-model sandboxed architecture. Built to explore and teach LLM security patterns.
This is a capture-the-flag style playground for testing prompt injection attacks against progressively hardened LLM defenses. Each of the 7 levels has a secret phrase embedded in its system prompt, and the goal is to extract it.
All 7 levels are handled by a single API route. Each level defines its own system prompt, defense strategies, and difficulty rating. The two-model architecture in Level 6 makes two separate OpenAI API calls: one to generate the response and one to evaluate whether it leaked the secret.

Interested in working together? I'm always open to discussing new projects and opportunities.
An open-source scheduling platform I built to replace Calendly for my own use. It connects to Google Calendar, merges availability across multiple calendars, and lets people book meetings through a clean public link. Includes AI features for generating event descriptions and follow-up drafts.
A streaming RAG-powered knowledge search tool that lets users ingest their own documents, runs paragraph-level embeddings, and returns grounded answers with source citations in real time. Built with OpenAI embeddings, GPT-4o-mini, Supabase pgvector, and a Next.js 16 API layer.
An AI-powered voice kiosk platform I built at Interactive Knowledge. Each deployment is a themed character that visitors talk to using natural speech. I built the React frontend (167 of 196 commits) and contributed to the headless Drupal 11 CMS. Built with React, OpenAI, Google Cloud TTS, and Web Speech API.
