Our Apps team is driven by the sheer passion to create security-enhancing apps. We build products that make cybersecurity easy and accessible to everyone. But making sure users have the smoothest experience using our apps is what really drives us. So we continuously run UI tests and implement large transformations in small increments to maintain a fresh codebase. Combine this with dedicating time to make the code pretty, and voilà! That’s a recipe for success.
