"you're not hiring for roles anymore. you're hiring for breadth + depth, taste, systems thinking, learning velocity. 5 people who can work across code/design/product beat 20 specialists coordinating handoffs." - Ryo Lu on X. I can strongly relate to this. In my experience, when I was working across domains, I could do a task alone in 2 weeks that would take two engineers 4 weeks to complete. The coordination, hand-offs and cross domain language barrier costs are real.
