I think it's weird that you consider my code more CS than engineering
My bad. I'm stereotyping your code based on the subject matter: parsers and the surrounding ecosystem. That area of expertise has always seemed to be dominated by academics, in my experience.

I occasionally do work on the side from my M-F/8-4 job. One job was for a university professor who used graduate students as slave labor. They needed a multithreaded app to setup and control some hardware they were developing for sale outside the university. There was quite the culture shock when I started submitting code to them. They were used to using and writing code that started with the bare minimum necessary to perform some function, and then layered error handling and UI on top. The notion of architecting a solution in advance that kept these considerations in mind was utterly foreign to them.

The more noteworthy job was software to run a prototype machine. An intern at the company had written hardware control primitives that were quite good. A scientist wrote code that performed the detailed mathematics required to execute the machine's actual function. The scientist was a good mathematician, but a terrible programmer. I was hired to write a test bed application to let the company demonstrate the hardware to their customer. I wrote UI and integrated the intern's hardware primitives in short order. Integrating the mathematics was a disaster. I routinely set the warning level on my compilers at maximum just ensure that the stupid mistakes are caught. The scientist's code wouldn't compile clean, even at warning level zero. Lots of ill-advised pointer arithmetic, a global misunderstanding of type casting, random switching between float vs. double, a firm belief that array indices in C started at 1 (see the pointer arithmetic), and so on. I tried to work around the problems for a while, but finally gave up.

The scientist wouldn't give me a copy of his design notes for the mathematics, so I finally went to the head of the project for them. Between those notes and reverse-engineering his code, I was able to replace the mad scientist code with something a lot more robust. Interestingly this was one time in my career where my courses in numerical methods in college really came in handy. I replaced some of the scientist's integration and differentiation code with other algorithms to address precision issues. I even found some operational errors in the design as I coded the replacement. Since this was a prototype and a demonstrator, it wasn't too hard to make the code switchable to demonstrate the original mathematics versus mine. Since the original math crashed the app well over half the time, or took minutes to produce a result, and my code took a couple of seconds and never crashed, it made an impression.

The funny part of the whole thing was that I didn't know anything about the problem domain that the math was being used in. I just knew when the syntax of the operations being performed didn't make sense (multiplying a 5x7 matrix by a 4x3, for example), or that the order of operations was likely to cause an overflow or underflow, or that units conversions were not being handled correctly.
