Office Hours

Come attend scheduled, live Office Hours with iOS, Android and Flutter experts that can help answer your development questions.

Have you ever been stuck on a problem and wished you had a senior developer to talk to?

Maybe you’re not sure what the best architecture is for your app; perhaps you can’t quite wrap your head around reactive programming; or maybe you’re trying to decide between use Flutter or native development for your next project.

Not everyone has easy access to a senior developer, especially when everyone seems so busy these days and our teams are more physically separate then ever before.

Good news: Office Hours are the next best thing to having a senior developer right next to you!
