About

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

Some frontend focused projects....

Using AI

This is 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.

Landing Pages

My first tool under the Using Ai ecosystem. This is a tool that will generate a landing page template based on a few buttons and prompt. It provides a clean and simple interface for creating landing pages templates. Allows for exporting the html for further customization.

Auidophile

My first large project with a framework back in 2019. It was a challenge project from the website frontend mentors. Decided to use Next.js with TypeScript and Tailwind for this one. Still use these things today.

Some backend focused projects....

Prep App

This is a fullstack application in Rust, my favorite language. Tried to go as minimalistic as possible, and had a ton of fun. Was hosting this on an amazon ec2 instance, but cost was not worth it.

Recipe Api

Wanted to explore PHP and Docker. PHP is an appealing scripting language for backend applications, specifically APIs that service web applications. Docker is a great modern tech that simplifies the deployment of applications.

Yafa

The stock market is full of data that can be used in various ways. This particular project uses a Rust Api to get data and transform it into views. Got a chance to use Bun.js with TypeScript.

random space parts

Some open source focused projects....

Brize Auth

A simple auth server in Rust. Still a work in progress, but functions really well as is. Built for MySQL and SurrealDB databases for now. Was a good project to understand how authentication works at a low level.

Alpaca Api

Alpaca is a service that provides endpoints for stock market data. They do not have an official Rust SDK, so I scrapped one together.

Tindi

I made a simple technical analysis indicator library in Rust. It uses various algorithms to generate technical indicators which are stock market signals to buy and sell.

Some machine learning focused projects....

Tabular Binary Classification

A tabular binary classification project using the classic titanic dataset. This was my first attempt at tabular binary classification, and I am happy with it. Used the Burn crate from the Rust ecosystem and submitted to Kaggle.

Natural Language

An attempt to train an NLP to classify patent types. The training did not create an accurate model honestly, but was a great experience using the Transformer neural network architecture.

MNIST Digit Classifier

This is the case study of the classic MNIST dataset which contains 70,000 images of handwritten numbers. This was a good lesson for creating a neural network from scratch, as well playing with custom loss functions.
