What kinds of technical challenges do you and your team face?

One challenge my team faces is staying ahead in the ever-changing tech landscape. We’re tackling this by building a library of widgets, or carefully designed, reusable pieces of code, so we can keep our tech stack dynamic. The goal is to be able to plug these widgets into any of our products, reducing redundancy and keeping things loosely coupled.
