5. @magdamiu OOP 01
6. @magdamiu • DRY - Don’t Repeat Yourself ◦ Applicable whenever we copy / paste a piece of code • KISS - Keep It Simple and Stupid ◦ Whenever we want to implement a method to do all things • YAGNI - You Ain’t Gonna Need It ◦ Don’t write code which is not yet necessary • SOLID ◦ Single responsibility (SRP) ◦ Open-closed (OCP) ◦ Liskov substitution (LSP) ◦ Interface segregation (ISP) ◦ Dependency inversion (DIP) Design Principles
7. @magdamiu Design Patterns
8. @magdamiu Kotlin 02

21. @magdamiu Learning Plan 05
22. @magdamiu The “process” SWOT Where I am now Retro How it was and what’s next OKRs What I want to achieve Review What I achieved 01 02 04 03
23. @magdamiu Step 1 SWOT Where I am now
24. @magdamiu Personal SWOT Analysis Strengths Advantages like: skills, achievements, certifications, education, connections Weaknesses Skills that should be improved (technical or work habits) Opportunities Events, conferences, new role/project, industry growing Threats Impediments at work, changes, weaknesses lead to threats S O W T Here you can evaluate your profile
25. @magdamiu Step 2 OKRs What I want to achieve

27. @magdamiu Superpower Focus and commit to priorities Superpower Align and connect with your goals Superpower Track for accountability 1 2 3 OKRs superpowers 4 Superpower Stretch for amazing
28. @magdamiu OKR sample Learn Kotlin for Android Development 6 months / weekly review Quantity Goal Quality Goal Result 1 Kotlin Koan per week Learn specific features of the language => 1 feature / week Exercise often and on a set of Koans proposed by JetBrains Write one detailed article about a specific topic per month Improve my writing skills and learn by teaching to others Learn new things, help the community and get feedback 3 code samples runned per week Get a repo with samples that I can re-check (use ktlint) Gain real experience in programming using Kotlin
29. @magdamiu Step 3 Review What I achieved
30. @magdamiu • Score your results • Keep notes of your accomplishments • Look for feedback because development is continuous • Surround yourself with people who motivate and inspire you • Find a mentor Review process
31. @magdamiu Step 4 Retrospective How it was and what’s next
32. @magdamiu • Did I accomplish all of my objectives? ◦ YES => what contributed to my success? ◦ NO => what obstacles did I encounter? • Understand what is your WHY • Repeat the process Retrospective
