Application Development

In Pursuit of Developer Happiness

1. Application Development Pursuit of Developer Happiness
2. About Me !   Tom Wilson !   Chief Technologist, Jack Russell Software !   A division of CareKinesis, Inc !   Building Applications and Development Teams for 15+ years
4. Experience I have made more mistakes I have tried to learn from them
5. I want to create an application that is just as easy to maintain as it is to create
6. long road no silver bullet
7. Three Approaches
8. Approach 1
9. BDUF !   Review all systems in the market !   Bring users from each system to provide features !   Use new platform !   Set unreasonable goals !   Add developers as needed
10. result
11. System of Systems !   Complex difficult to !   Support !   Maintain !   Upgrade
12. Approach 2
13. Waterfall to Agile !   Started with complex Data Model !   New Web based interface !   New Dev Environment !   Small Team !   Implement and ship incrementally
14. Success! kind of
15. Results > SOA !   Complex !   easier to support !   easier to upgrade !   still hard to develop !   tightly coupled components
16. Approach 3
17. Agile to Waterfall !   Launch MVP !   Continuous Deployment !   PAAS !   Extreme Programming !   OpenSource Stack
18. Awesome
19. Too Extreme! !   Users wanted slower pace !   batch features !   more stability !   more process
20. Enter Waterfall But we still called it Agile!
21. “Afraid to admit we are Waterfall”
22. we are awesome!
23. results !   huge backlog !   easy to support !   easy to upgrade !   painful to develop
24. Lessons Learned
25. avoid configuration as much as possible
26. clearly define your features Know your user
27. App Analytics !   mixpanel !   kissmetrics !   new relic
28. Loosely Coupled
29. Events, APIs and Bots !   activity stream !   trigger tasks from activities !   Http/json
30. Think in terms of Applets and Components
31. build a collection of apps
32. Applets and Bots
33. Our New Approach !   Quarterly Goals !   2 week sprints !   javascript everywhere !   connect devs with stakeholders !   PAAS
34. 2 week sprint !   2 days planning – redact stories to product team !   4 days dev !   2 days code review !   2 days qa
35. Javascript Everywhere !   AngularJS !   NodeJS !   Npm !   Browserify !   CouchDb
36. Devs should be involved from concept to completion
37. PAAS Dev should have their own personal playground to explore and share concepts
38. Prototype to Production
39. Just do it Do it Fast Do it better
40. Prototype !   Bootstrap !   AngularJs !   Firebase or PouchDb !   Collaborate RealTime
41. Early Adopter !   Sames as Prototype !   Add NoSql Backend Mongo, CouchDb !   NodeJs !   Clearly Separate Concerns !   Bots and Job Queue
42. MainStream !   convert to Applets and components !   Focus on Polish and Usability !   Product Boundaries !   Measure Everything !   Formalize Schemas {sql}
43. Dev Goals !   Design in Real-Time (if possible) !   Applets and Bots - Microservices !   Flexibility and Durability !   Javascript everywhere, until necessary
