Often times the hard work done at the foundation level is ignored and underappreciated, while the surface / presentation work is easily spotted and praised by the bystanders. Yet without the foundation work, the surface work would have never been there at the first place.
You praise a house with nice interior design and furniture. You don’t praise a house with stable electricity and water access – that’s a given; yet when the water leaks, guess who gets the complains?
With similar logic, the first engineer who make the code work gets all the credits, even in the sluggish and ugly way. Whereas the next one that tears it apart, refactors to makes it better, more scalable doesn’t get quite as much credit. Yet it’s debatable which course of work is more difficult.
And in lots of case, scaling something up is miles more difficult than just making it work.
