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.
