Work Experience

Senior Full-stack Developer

2016 - 2020
Atados
  • Introduced Jira, Scrum, and pull request (PR) reviews to synchronize our team and guarantee quality.
  • Created a ticket system that every internal request had to go through. This helped our team keep track and respond to everyone, gathered the required information, and reduced friction.
  • Reduced infrastructure costs by 50% through server migration, better caching on the front end, improving the deployment system, and transforming the most viewed pages from dynamic to static pages.
  • Unified clients' apps with a new product version that automatically integrated all modifications in one repository. This improved digital transformation (DX), thus reducing the time to release new updates.
  • Drove a 37.5% growth in sales by internationalizing the product to sell outside the country.
  • Refactored the front end, moving from Angular to React, which reduced the time to render the app from 4.5 seconds to 200 milliseconds and improved the mobile experience that represented 56% of sessions.
  • Developed the white-label system that enabled the company to scale its platform to large companies. When I left, the OVP platform was running at 11 companies.

Junior Full-stack Developer

2015 - 2016
Foxx Tecnologia
  • Developed a student management system and a reports system that kept track of data on 400+ students. Both were part of the startup's main product, a Sass web app to manage schools.
  • Created a relations map of a 50-table database with no indexes to build a report that crossed data and produced a human-readable report, allowing the client to fetch the values they needed. This challenge sat for three months before I took it on.
  • Developed a restaurant web app with CakePHP that processed 100+ orders per day.

Experience

White-label Volunteering Platform

https://atados.com.br
A React-based web app to empower social projects. Project creators used it to find and manage volunteers and receive donations through a payment integration. On the other side, volunteers could match themselves with projects and follow a volunteer path.

I was the main front-end developer and liaised with the back-end developer to integrate with our API on our main product and in client-specific platforms. For the payment integration, I worked as the back-end developer, where I created Lambda functions to serve as our integration bridge. It allowed us to receive R$200,000+ (Brazilian real) in March of 2020. I also worked as a back-end developer to enable our white-label features. In this role, I created a system where a platform for a client could easily overwrite parts of our app to function according to the client's needs.

To improve the development experience, I added continuous integration to improve the deployment process. The integration validated the new app version, deployed previews, and guaranteed that every client was up to date with the app core.
