3. Lean Startup
4. Lean Startup Startups require an MVP to validate their ideas In Early Stages, Startups spend a lot of time trying to find good developers with enough experience to build the MVP
5. But Experienced Devs cost a lot of money and they hire Junior Developers
6. How to recognize a good developer? A good developer looks for challenges, for continuous learning
7. Even as Junior, these developers must know some key concepts to start their work
8. SOLID principles
9. SOLID Principles Follow these principles help you to avoid that any change you have to do, break any other feature on your app.
10. SOLID Principles • Single Responsibility • Open/Close Principle • Liskov Substitution • Interface Segregation • Dependency inversion https://apiumhub.com/es/tech-blog-barcelona/principios-solid/
11. Design Patterns
12. Design Patterns You don’t need to invent the wheel again, many design problems could be boarded using design patterns. The design patterns are proven strategies to solve common problems.
13. Design Patterns Creational Behavioral Structural

15. Clean Code
16. Clean Code Follow standard conventions. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible. Boy scout rule. Leave the campground cleaner than you found it. Always find root cause. Always look for the root cause of a problem.

34. UI / UX Don’t make me think Self-evident Obvious Self-explanatory

36. As Developer or CTOs, we MUST leave the office
37. As Developer or CTOs, we MUST leave the office A better comprehension of how our product works, it’s possible not only waiting for feedback from our customers, we should use that we built. “The shoemaker's son always goes barefoot.” This expression does not apply to us. Read the feedback received through App Store or Play Store MUST BE read. Every negative review should be investigated
38. Developer Stack Tools & Components
39. Developer Stack - Tools & Components Kotlin Programming Language It’s not only the best choice technically speaking even business https://kotlinlang.org/ Architecture Components https://developer.android.com/topic/libraries/architecture Retrofit https://square.github.io/retrofit/ RxJava o LiveData + Kotlin Coroutines https://github.com/ReactiveX/RxJava
