Software Bootcamp graduates (and other Junior Programmers) are entering the technology market with a brief understanding of CRUD actions and web development in general. After a whirlwind of learning in school, graduates are often left asking: what do I learn next? My first professional project was to create a microservices app from scratch. Previously, I had made extremely simple apps with only a few models, a couple of controllers, and some basic CRUD actions. Oh, and static web pages. I made plenty of those. This talk covers some of the key technical concepts encountered when first going beyond a basic crud app: * State Machines * Decorators * Database Normalization This talk will also discuss some of the soft skills that are necessary to participate on a software development team, including: * Code Reviews * User Stories * Pair Programming Bootcamps are a clear line from civilian to Junior Programmer. Less clear is the line from Junior to Mid-level. Armed with basic CRUD and MVC knowledge, Junior Programmers can begin to dive into other programming concepts. Programmers are also expected to participate in collaborative development on projects that require soft skills in addition to technical skills.

2. Leaving Bootcamp
• MVC
• CRUD
• Small Apps
• Small teams/projects

3. Employers hire bootcamp
grads for their potential

4. What to Expect When You are
Programming
Tools of the Trade
✦ User Stories
✦ Pair Programming
✦ Code Reviews
New Concepts
✦ State Machines
✦ Presentation Layer
✦ Data Modeling

5. User Stories

6. Template

7. Types of User Stories
• Features
• Improvements
• Bugs

8. Who Writes User Stories?
• Business Analysts
• Developers
• Designers
• Product Managers
• Whoever finds the bug

9. Estimation
• Broader == Less Accurate estimates
• Estimation is hard
• Estimation is even harder as a junior engineer

10. Acceptance Criteria

11. KanBan Boards

22. Who reviews code?
• EVERYONE!

23. Junior Recaps Concepts

24. Senior Reviews Junior

25. Best Practices
• Critique, don’t criticize
• Before implementation
• Teaching moments
• Review often
• Ask questions

26. Conceptually Going
Beyond CRUD

27. Presentation Layer

28. Task
• Reduce logic in views
https://github.com/drapergem/draper

29. Presentation Layer improves the
“V” in MVC
• View Partials: Code reuse
• Remove view logic from models
• Remove business logic from views

30. Remove View Logic from Model

31. Conditionally Show a Header

32. Put them together…

33. Sometimes what we present
is JSON, not HTML

34. API Entity

35. State Machines

36. Task
• I want applicants to see where they are in the
application process
• I want admins to be able to perform some actions
based on other actions

37. Junior Dev Solution
• multiple boolean fields
• long conditionals

38. State Machine Solution

39. Business Logic

40. Implement Business Logic
Admin can reject anytime during the process
Can only be hired IF have been interviewed
https://github.com/aasm/aasm

41. Applicant Views State

42. Admin Views State

43. Data Modeling

44. Task
• Geocode the address

45. Junior Dev Solution

46. Thought about…

47. Refactor

48. Normalized

49. Other concepts
• Ternary Operators
• Inheritance
• Composition
• Asynchronous tasks
• Continuous Integration
• Session variables
• Unit Testing
• Test Driven Development

50. Summary
• Stimulate or Stagnate
• Always Be Learning
