Productive

https://productive.io/
Productive is an agency management web application written in Ember.js with a mix of JavaScript and TypeScript. My biggest accomplishment on the project was migrating it from JavaScript to TypeScript. I also implemented numerous features on the project that improved the application's user experience.

Underline

https://underline.io/
An education application used to organize virtual conferences worldwide with thousands of users. I came to the project as a technical lead, so I was responsible for the tech stack, standardizing coding practices, giving estimates, and mentoring less experienced colleagues.

The most significant achievement I made on the project was when COVID-19 came, and I developed a Zoom-like feature on it to allow the client to have virtual conferences in less than two months.

JavaScript Multiplatform Framework

We built a multiplatform JavaScript framework that generated native web, Android, and iOS applications based on JSON configuration and minimal business logic. I served as a tech lead and principal JavaScript engineer on the project.

My job was connecting the business logic layer with native ones—React, Android, and iOS. I was also responsible for writing React components that were rendered based on the configuration. In the end, the framework generated around ten white-label applications for different domains, from eCommerce to IoT.
