Non-Technical

Consulting vs Contracting

• Greenfield vs Brownfield

  • Greenfield software is the software that we design and develop from scratch. Brownfield software is one where something already exists and we have to add functionality and/or features to it.

  • Obvious mostly works in greenfield software development but we occasionally work with brownfield stuff too.

Engineering Philosophy

• ​First Principles​

• Documentation practices (ADR, project documentation etc.)

Technical

• ​Trunk Based Development (TBD)​

  • Use of feature flags for features that span over multiple PRs

  • Habit of raising PRs everyday

  • Prioritising review over writing new code (dropping everything to review a PR)

  • Show the Simple repo for daily branches, continuous integration and Github Actions for having checks in place

• ​Code Reviews & Pull Requests​

  • Read the Google code review guide and highlight some important practices that we follow as a team

• Estimation Practices

  • How engineers get estimations wrong?

  • Estimation based on complexity and not time

• Testing

  • ​Testing pyramid

    • Unit and Integration testing

    • Importance of testing

  • ​Covariance and contra-variance in tests​

  • Testing codelabs for beginners:

    • ​Testing basics​

    • ​Test doubles and dependency injection​

  • ​Test doubles: Fakes, mocks and Stubs
