Project made with VueJS and Typescript.Developed a new feature in a app where users could do simulated exams online. The feature allowed the user to choose which language variant their simulated exams would use. To accomplish it I had to do some small changes on the Vue js client, adjust the functionality on the endpoint in the service, alter the table within the database and do a migration within our data.Participated in a workforce where we should maintain a React webapp on ENEM's Day and get new leads for Descomplica. I've made load tests utilizing Locust and Terraform to guarantee that the platform would be able to withstand the 30.000+ simultaneous access we were expecting. Also the app got around 10.000 new leads.And finally participated on the team that was maintaining Descomplica's main platform on web. We developed a new feature that would help students get adequate courses based on their knowledge. To do it we shipped several code to the frontend React client utilizing feature flag so nothing would break to the end user while adding the necessary endpoints on the backend. Made some significant optimizations to some old queries that dropped cpu usage roughly from 90 percent to 10.Worked on my first major project where we refactored Descomplica's main apps, which were natives, into a React Native Project with a team of only two developers. The app consisted of a platform for watching video lessons and live lessons, with a real time chat and moderation. Having features such as offline usage with cache management and download of lessons. The app was delivered with a working CI/CD with bitrise and code push for deployment and Jest for testing. Show less
