Topics Covered This Lecture

SOLID Principles & Design Patterns

Git Workflows & Code Review

Testing: Unit, Integration, E2E

Agile/Scrum for AI Projects

📖 Lecture Overview

This first lecture establishes the foundational framework for Software Engineering Principles. By the end of this session, you will have the conceptual grounding and practical starting point needed for the rest of the course.

        Why this matters
        Learn the software development lifecycle, SOLID design principles, version control workflows, testing strategies, and agile methodology for AI projects. This lecture sets up everything that follows — make sure you understand the core concepts before proceeding to Week 2.
      

Key Concepts

The lecture introduces the four main pillars of this course: SOLID Principles & Design Patterns, Git Workflows & Code Review, Testing: Unit, Integration, E2E, Agile/Scrum for AI Projects. Each will be explored in depth over the 14-week curriculum, with hands-on projects reinforcing theory at every stage.

# Quick Start: verify your environment is ready for SE101
import sys
print(f"Python {sys.version}")

# Check key libraries are installed
try:
    import numpy, pandas, matplotlib
    print("✅ Core libraries ready")
except ImportError as e:
    print(f"❌ Missing: {e} — run: pip install numpy pandas matplotlib")

This Week's Focus

Focus on mastering: SOLID Principles & Design Patterns and Git Workflows & Code Review. These are the prerequisites for everything in Week 2. The concepts build on each other — do not skip the practice exercises.
