About

Hi, I'm Jon.

Another programmer on another slice of the internet. Probably solving another problem, or creating another thing. I love it, and will do it in a loop while alive is true. Take a look around at some of my stuff, or just say hi.

Projects

Things I've built

Some frontend focused projects.

Using AI

The central hub for my suite of AI-focused products. The purpose is to provide a landing page for marketing and education. My goal is to provide every-day tools that leverage AI, and wrap them in an easy-to-use interface.

Bernt

An iOS app that plans your meals around the ingredients you already have. Talk to it in plain English, tell it what's in your pantry, and it writes the week's recipes and grocery list for you. Less thinking, less food waste, more cooking.

Lernt

An AI-powered learning platform that turns a one-line prompt into a full course. Any topic — Python, philosophy, music theory — gets a structured curriculum with adaptive exercises and quizzes scaled to your level. Self-paced, no credit card to start.

Some machine learning focused projects.

Market Runners

AI-driven market intelligence delivered through Discord. Multi-model pipelines ingest live equities, crypto, and macro data to emit signals, sentiment, volatility flags, and daily briefs. Built for retail traders who want machine-graded context, not buy/sell calls.

Magic Price

A Magic: The Gathering card pricing API. An ML model trained on 100,000+ cards serves fair-market predictions for collectors, traders, and deck builders. Query by card, get a number.

IPO Case Study

An exploratory data analysis of IPO returns. Jupyter notebooks walk through cleaning, feature engineering, hypothesis testing, and visualization, with the findings written up in a formal report.

random space parts

Some open source focused projects.

Brize Auth

A simple auth server in Rust. Work in progress, but functions really well as is. Built for MySQL and SurrealDB. A good project for understanding authentication at a low level.

Alpaca Api

Alpaca provides endpoints for stock market data. They don't have an official Rust SDK, so I scrapped one together.

Tindi

A simple technical analysis indicator library in Rust. Uses various algorithms to generate technical indicators — stock market signals to buy and sell.
