After defining an algorithm for this, we codified it into a theme generator script which generates output for all platforms: XML for Android, JSON… Read more
Implementing Event Tracking Infra with CDK
Engineers at Wealthfront emphasize iterative development and maintainability of code to build robust applications. The underpinnings of any application is its infrastructure. To build robust and scalable apps, it is a requirement to apply the same engineering principles of iteration and maintainability to create quality, underlying infrastructure. In the case of our event-tracking system, which… Read more
