3 engineers arrived - fashionably late. We explained them the situation and all we wanted from them was some GCP offering that would cure our woes and one that would cut our bills. The senior consultant - and presumably the only tech guy (rest seemed to be salesy) wasted our time like a used car salesman - he didn't even understand Google's own product portfolio and recommended us to use something like Spanner - which was totally not the solution to the problem, not to mention, expensive.
My boss and I left the meeting pissed off and he told me - "Neya, you probably know more about the product portfolio than these guys. Let's leave". That weekend, I went with my tried and trusted favorite Db - PostgreSQL - CloudSQL with a custom Elixir middleware based an old CMS I wrote a decade ago. After some trial and error, the solution worked flawlessly (and still does till date on auto-pilot). My client still has the lowest cost in the region - 1/3rd the cost of their competitors...7 years later. Back then, there was no vibe-coding, no AI, no auto-completion. Just pure thinking and experimentation.
All this just to say I agree that the new guy sometimes can make the best solutions to a problem and not always screw up. I always listen to new hires these days (now I'm a fractional / CTO) because you never know who could pull off that 1/3rd cost cutting framework move.
Sometimes those complex solutions are the right tool for the job. And other times, you just need to glue some stuff together, call it good, and start making money.
Experience helps a good engineer know when each approach is appropriate.
