80 / 20 principle in Sofware Development

The 80/20 principle (Pareto Principle) states that 80% of outcomes come from 20% of efforts. You can leverage this principle to accelerate your journey to becoming a Senior Software Developer, System Architect, and Lead Developer by focusing on high-impact skills and activities. 1️⃣ Become a Senior Software Developer (80/20 Focus) A Senior Developer is an expert in coding, problem-solving, and software design. To reach this level, focus on high-leverage activities: Step 1: Master Core Technical Skills (20%) → 80% Impact Deepen Your Expertise in One Tech Stack Focus on Java + Spring Boot (since you already use them).
