❌ No PhD ❌ No model training from scratch ✅ Just knowing how to work with LLMs to build real products
I sat down with Nikhil from Perplexity to break down: – What AI engineers actually do – How he pivoted from full-stack to AI – And why this role is suddenly everywhere
🚨 Ever wondered how ticket scalpers make millions? 🚨
In my latest video, I tried the world of ticket reselling, revealing what really goes on behind the scenes—from Ticketmaster crashes to secret broker networks. I share my personal journey of trying to break into the industry, the challenges I faced, and the shocking truths I uncovered along the way.
Check it out to learn how the system works, what went wrong with my attempts, and why it's not as easy as it seems! 🎟️💸
