The Profile Builder was the project for one of the biggest technological stock exchange in the world. We have worked remotely as an agile team with the client from USA, New York. The project was about helping people who work in financial area to easily build financial reports with dozens of formulas that have to be calculated at runtime. As well, the report generation engine had to support different formats like Excel, Word, PowerPoint or PDF. Besides, one of the parts is an integration with external partners, as they have important fresh financial data that needs for customer formulas. This was a challenging project, as one of the requirements was to support more than 10.000 corporate clients (as an example the whole Google is just one corporate client).
