TechPulse – Building a Scalable Tech News Analytics Platform | Phase II: System Design
Before writing a single line of scraping code, we answer the most important software engineering question:
How will data flow through our system?
In this video, we design the complete architecture of TechPulse, an end-to-end Tech News Analytics Platform. Instead of jumping straight into coding, we first build a scalable system that can support multiple news websites, thousands of articles, and future expansion.
In this video you'll learn:
Why system design comes before coding
Designing an end-to-end data pipeline
Breaking the project into components using the Single Responsibility Principle
Choosing the right tech news sources
RSS feeds vs direct web scraping
Designing a common schema for multiple websites
Building a reusable scraping framework instead of individual scrapers
Database design from a business perspective
Identifying entities and relationships
One-to-Many and Many-to-Many relationships
Bridge tables and database normalization
Designing a scalable MySQL database
Creating an Entity Relationship Diagram (ERD)
Planning for future scalability (50+ websites and 100,000+ articles/day)

This series focuses on building software the way it's done in production—not just writing scripts, but designing scalable systems using real software engineering principles.
One of my biggest takeaways from this phase:
Beginners build scrapers. Experienced engineers build frameworks that can support many scrapers.
