1 year as a software engineer at Amazon. Previously interned at Microsoft. Been building AI applications on the side since 2023. Here's the most important thing I've learned: The engineers who grow fastest aren't the most talented. They're the ones who consistently learn from people with 10-20 years of experience. They don't just attend design reviews — they ask questions in them. They don't just copy patterns — they understand why the pattern was chosen. They don't just ship features — they understand the system those features live in. AI makes it incredibly tempting to skip this step. Even I struggle with this from time to time You can generate code, build features, and ship products without ever understanding the "why." But the "why" is what makes you irreplaceable. In a world where AI can write code, the people who understand why the code should be written that way become the most valuable people in the room. Don't just build. Understand what you're building. That's the real competitive advantage.
