He then switched to the front-end and now uses HTML, CSS and JavaScript to create user-friendly apps. He is well versed in integrating any of the Firebase tools into your application whether you just want to use hosting to take advantage of Googles extensive CDN or you want to include authentication, storage, databases and cloud functions to really make your web app shine. Dave can make your website feel like a native application by taking advantage of Angular's extensive tools and services. This has the added bonus of only needing to manage one product that will work on any device from mobile to tablet to desktop. If your product requires native phone technologies Dave can use Ionic and Capacitor to turn your web app into an Android or iOS app giving you access to tools like push notifications, the camera and GPS.
