Pension Plan Calculator
A React/Node.js app for planning out retirement goals. I was the front-end developer who had to work together with the back-end programmers to deliver an app in which users could calculate how much money to put into different pension plans to reach a certain income when they retire. I had to set up the interface and logic for the calculator as well as the different flows for each type of plan.
