Don’t overcomplicate it.
• Build a Password Manager to learn file handling, hashing (not full crypto)
• Build a URL Shortener to understand routing, IDs, and persistence
• Build a Todo App with deadlines to practice CRUD and basic state
• Build a Web Scraper to learn requests, parsing, and rate limits
• Build a CLI Expense Tracker to master logic, files, and edge cases
• Build a Log Analyzer to work with files, timestamps, and patterns
• Build a Simple Recommender using similarity rules (not ML magic)
• Build an Email Automation Script using SMTP and scheduling
Projects. Not tutorials.
