Projects
Things I've built
ProofPass
On-chain compliance identity and audit system for autonomous AI agents trading prediction markets. Each trade mints or updates a Solana NFT passport, pins a tamper-evident audit log to Filecoin, and pays for inference via native HTTP 402 machine-to-machine micropayments. Built for the Penn Blockchain Conference.
Memecoin Alerts
Python-based Telegram alert bot for tracking new Solana memecoin opportunities. It polls DexScreener for fresh token pairs, filters candidates by liquidity, volume, market cap, and age, checks RugCheck risk scores, and sends alerts for tokens that pass configured thresholds. Supabase Postgres persists token tracking to prevent duplicate alerts across scheduled GitHub Actions runs. Visit it at @JoelMemecoinAlertBot.
Quantitative Trading Simulation Engine
Monte Carlo risk simulation system supporting Value-at-Risk (VaR), Expected Shortfall (ES), and full P&L distribution modeling with delta-normal, delta-gamma, and historical risk models.
Word Par
A golf-themed Wordle-style game with OpenAI-powered semantic scoring. Features Express routes, authentication, a PostgreSQL schema for users and leaderboards, and server-rendered UI with Handlebars.
Personal Portfolio Website
Designed and deployed this responsive portfolio website showcasing projects, experience, and technical skills, with interactive JavaScript UI components.
Library Database System
Relational database system supporting book catalog management, checkout/return workflows, and patron records. Includes PL/SQL stored procedures and triggers for automation.
