My latest project. A search UI that pulls in live concert recordings from archive.org's API.

Features include a custom JavaScript music player and access to thousands of live concert recordings.

App also features a custom visualizer made by connecting to the browser's audio api and dynamically display a visual representation of the frequency of the sound waves for whichever song is playing.

The front end is built in React with HTML, CSS and TypeScript. The back end is built in NestJS, a Node based JavaScript framework. Check out the GitHub repo for the back end.

Visualization of historic stock and crypto prices.

Search for stock or crypto prices and view data in line graph format. Includes ability to view high, low, open and close prices. Users can hover over data points for more detailed information.

Users can view stock prices from NASDAQ and NYSE stock markets. Crypto coin types include BTC, ETH, BCH, LTC and more.

Data provided by Alpha Vantage's API. I'm using the free tier so it may run out of requests (it resets every day).

Built in React with D3, Redux, HTML, CSS and JavaScript.

One of my older projects. A search UI that pulls photos from NASA's image API. Users input search terms into the search bar and results are displayed below. Includes two different views, grid and list.

When the user inputs a serch term and hits Go, the front end makes a call to the back end which then makes a call to NASA's image API. Results are returned the backend, procesed and sent to the front end where they are then displayed.

The front end is built in VueJS with HTML, CSS and JavaScript. The back end is built in ExpressJS, a Node based JavaScript framework. Check out the GitHub repo for the back end.
