Professional Bio

I've always liked everything about computers. I decided to become a software developer because I realized I could do more than simply use them, but also create with them. I love finishing an application and seeing all the things that I dreamed become real — and better yet, watch as it is used by others. I've helped car companies speed up the process of acquiring and selling inventory, gamers buy access to games with cryptocurrency, and banks run their branches. My favorite language is JavaScript because it has so many excellent frameworks, like React, React Native, Angular, and Node, which can be used to create just about anything imaginable. In my free time I love to listen to music, watch movies on Netflix, and play games on my Nintendo Switch.

Mid-Level Software Engineer

At FullStack Labs, I'm responsible for developing robust web and mobile applications for clients around the world. I'm currently working on:

  • ScoutIQ, an app that lets Amazon merchants identify potential profits before acquiring merchandise. I optimized the app to speed it up and introduced new features, such as a function to scan multiple items. The web and mobile apps are being written with React and React Native, respectively.

I previously worked on:

  • ReconVelocity, an app to expedite the acquisition and selling of inventory at car dealerships. I integrated new technologies like TypeScript and connected the app with Firebase services. The app was also written with React Native.

I spearheaded development of the company's first multiplatform app, which was built by a team using React Native and Redux.js.
  • Developed R-Sales, an application to automate sales and facilitate the scheduling of client visits by identifying client locations on a map. I migrated the web app to Angular.js and made general improvements and performance enhancements on the mobile app. In addition to Angular.js, the project used Python with Django, and Sencha Touch.
