Preston Wallace
Hey there!

I'm Preston Wallace. I am a Full Stack Software Engineer with a longstanding love for everything tech. I currently work as a Software Engineer at MNTN in what I absolutely love: Node.js and GraphQL on the backend and React on the front end. I build backend solutions that work with SQL databases (PostgreSQL, Sequelize) to efficiently manage large datasets. On the frontend, I create reusable components that can efficiently display and interact with this data. At night, I teach React, Node, Express, and many other things CS-related.

What I do

Front-end Development

I work mainly with TypeScript, React, and Apollo, creating Single Page Applications.

Back-End Development

Using TypeScript, Node.js, Express, and PostgreSQL, I build REST and GraphQL APIs.


I create using Figma and Photoshop. I love working with CSS3, SASS, TailwindCSS, and Styled Components.

Agile Development

I work iteratively and efficiently. I believe we can achieve so much more as a team.
