Software Development and best Practices

2. Software Development Life Cycle

3. Software Development

4. TG - Projects &
Ecosystem

5. Projects & Ecosystem - Challenges
- Multi-Base-Arquitectures
- Django (MVT), Laravel: (MVC)
- Flutter (State-Based Design), React (State-Based Views)
- Issues:
- Works on small projects
- In medium/large projects the architecture is limited.
- In medium/large projects it generates high maintenance costs (high coupling)
- Multi-Standards
- PHP, Python, JS, Dart
- Laravel, Django, DRF
- Multi-Nomenclatures for DBs
- Developer Standards
- Different workflow,
- Own standards, sometimes :)
- Multiple formats for the requests/responses - APIs (GraphQL / RESTful)

6. Projects & Ecosystem - TechGenies Foundation
- Onboarding
- Best Practices
- Guidelines for Development (php,python,js,dart)
- Guidelines for RESTful APIs
- Guidelines for Postman
- GitFlow
- Unify Architectures
- Flutter, React.js, React Native (Clean Architecture)
- Laravel, Django (Layered Architecture, DDD)
- Same naming conventions for DBs
- Code Quality
- Continuous Deployment (CD)

7. Onboarding

8. Software Development
Django/Laravel/React.js/Flutter
8h

9. Onboarding I
- Software Principles
- Rapid Application Development (RAD)
- Design Patterns
- Guidelines (Standards & Recommendations)
- PHP (PSR), Python (PEP), JS (Lints, Google), Dart (Google Standards)
- Common Packages (Django, Laravel, React.js, Flutter)
- Naming Conventions
- Directory Structure
- Testing
- Open API

10. Onboarding II - Open API
- RESTful Foundation
- Hypermedia (Hateoas)
- Guidelines
- HTTP Verbs
- Associations
- Handling errors

11. Architecture

12. Architecture?
Which one to choose?

13. Architecture
- Operational Architecture Characteristics:
- Availability
- Performance
- Reliability
- Low Fault Tolerance
- Scalability
- Structural Architecture Characteristics:
- Configurability
- Portability (share modules and libraries)
- Maintainability
- Cross Cutting Architecture Characteristics:
- Accessibility
- Security
- Usability

14. Architecture - Layered Architecture (Laravel, Django)
- Service Layer : Responsible
for representing concepts of
the business, information
about the business situation,
and business rules.
- Repository Pattern: Is a
Domain-Driven Design pattern
intended to keep persistence
concerns outside of the
system's domain model. One
or more persistence
abstractions - interfaces

15. Architecture - Clean Architecture (Reactjs, Flutter)

16. Architecture - Achievements
- Standardized Rest APIs for Django, Laravel (Requests/Responses)
- Same Endpoints for Django, Laravel
- Reusable Components/Widget in React.js and Flutter

17. Code Quality

18. Code Quality I - Challenges
- How code quality impacts the overall software quality?
- How the code quality can be maintained throughout the software? If that can
be done, what are the parameters to measure the software code quality?
- The developers are often seen side-stepping the quality when they are need to
complete their tasks in a very short span of time.
- When someone fails to heed the code quality, it can sometimes lead to
additional rework in the code. This can eventually enhance the cost of the
software.

19. Code Quality II - Revisions (PR/MR)
- Code quality refers to the usefulness and maintainability of the code in the
long term. It provides insights to the project managers about the coding
practices and style followed by a team of developers
- Code quality is considered as an essential investment
- High code quality can be one of the best ways to lower the technical debt.
- Pull Requests (PR) / Merge Requests (MR) are more important, Now :)

20. Code Quality II - Measuring

21. Continuous Deployment

22. CD - Git Flow
- Gitflow is simply
organizing the work
into branches and its
sub-branches.

23. CD - Workflow
- Support: Django,
Laravel, React.js
Projects
