Prod Ready Code

@UCa3hkz84WHT38855pZLCK0A - 13 subscribers

This is not another tutorial channel. This is an operating room for production code. We don't learn syntax here. We perform code autopsies, diagnose performance bottlenecks, and fix the bugs that keep your team up at night. With 8+ years on the front lines, I've seen the mistakes that cost companies millions. My mission is to make sure you don't repeat them. We don't just write code. We make it production-ready.
