Welcome to Day 2 of the "50 Days Software Architecture Class" on YouTube! Moderated by Anastasia and Irene, today's focus is on the key principles of software architecture, including modularity, separation of concerns, and the SOLID principles. The session is 15-20 minutes long (approximately 60 words per minute, total word count ~1150 with natural delivery). We've structured it with 20 slides, each featuring 4 bullet points and conversational scripts from both moderators. Anastasia leads slides 1-9 (intro, modularity, and separation of concerns), Irene handles slides 10-18 (SOLID principles, application, and pitfalls), and slides 19-20 are shared for recap and closing. This builds directly on Day 1's introduction. Pauses, transitions, and visuals will enhance the flow.BuyMeACoffee: https://buymeacoffee.com/dailyaiwizard
