The most amazing...
...project I've worked on was a web app that suggested the best stock opportunities for an investor, given his or her preferences.
Employment
Experience
- Top Stocks
This is a web application that suggests the best stock opportunities for an investor to buy, based on his or her personal preferences.
For example, the user could choose how much risk he or she was willing to take or what range of prices he or she would be able to afford. A custom algorithm would take all of the defined preferences and rank the stocks accordingly to them.
In order for the application to work, it had to fetch data from both the Brazilian stock market and from an analysis house that released information about companies each week.
The application was developed using React.js and Material-UI. - EIS Mobile
This project was a mobile application (for both Android and iOS) that managed electrical devices and energy consumption for a group of buildings. A manager could see data from charts, create tasks and assign them to workers. The workers would start working on the tasks and update their status. They could also write comments on them or attach images. There was an extensive suite of unit and end-to-end tests that were run on a continuous integration tool.
The application was developed using NativeScript and Angular. - Analyst Tools
This was a web application for aiding electrical engineers in their analysis of electrical devices. The engineers used to keep all the information on static spreadsheets. This app was created to substitute these spreadsheets and make their jobs easier by offering searching and filtering options. The main screen shows a huge heatmap of devices and their information.
The app was developed using React.js and Material-UI. - Olympics
A REST API for serving mobile and web applications for the Rio 2016 Olympic Games. This project had a very strict non-negotiable deadline. There were a lot of details regarding parameters, payloads, and response codes. It also had to be scalable to support thousands of users.
The API was developed using Java, Spring, and Oracle.
