What's the most complex program you've ever written?

Depends on your definition of complex.

I wrote console program for playing Sudoku in C. It even had a solver and could validate input.

That's not necessarily intellectually challenging, but I can share my most frustrating

I was given one month to refactor our data forwarder to support a new data source, keep all of our existing features and clean up the code. Code was super old, new data source had many features that made it near impossible to use with our existing data sources and it was a huge undertaking given size of code base and differences in data source assumptions. Met the goals at the end, but the new data source ended up not being needed. Took another week to gut out code and take only a fraction of the refactor. Code base was also very old so refactor was a bitch and a half. So I basically wasted 5 weeks, but meh. life goes on

I had to write a program that helped provide inverse reactive current, for use in unilateral phase detractors, but would also be capable of automatically synchronizing cardinal grammeters.

Hello world
I have wasted my highschool time with learning programming and then at university everything went okay until the last two years of the education. After that I had a paus from 2011 till now with doing nothing, not even looking at books or anything. So I am supposed to be "good" in the eyes of companies. However I am not, so I am never getting a job within the field I "devoted" myself to.

i made a simple proportion calculator in C but it was like
printf format is a/b = c/x
printf program finds x
enter a
scanf
enter b

enter c

then it calculated x

I was told to write a better ultra key for "greenscreening" as a favor.

Because the retarded producer interviewed a white guy on a white background, and wanted the white background gone.

I had no idea where to even start, googled adobe plugin tutorials, video editing libraries, and then just made slow progress (planning to make a key that just cuts out any non changing pixels and tries to guess if its outside the head, as the guy had black hair). As I hoped, he eventually got tired and hired an actual video guy to manually mask the interviewee for an hour and I was no longer needed.

I wrote a program that plays (simulates) Magic: The Gathering. It only plays Legacy Charbelcher, but it has first-turn "win" rate of about 35%. It learns from which moves lead to a win/loss, and favors the better options.

Would share source, but it's in embarrassingly-written Java, and I haven't finished the Lisp rewrite.

I'm currently creating a complex program in C that forks 4 child processes to read 4 different files, find prime numbers in those files, then write those numbers into 1 resulting file.

My two top spots are probably taken by an ARM7TDMI emulator (was working on a full GBA emulator, but got burned out after doing just the CPU), and probably a PDF parser used for some security stuff. The ARM emulator was the much larger of the two projects, though.

Ugh. This one time I had to optimize this legacy code for what was supposed to be a critical system that was written in fucking COBOL. About a month's worth of work with a deadline in 10 days. I wound up getting side tracked because I was convinced my meth dealer was actually a 14 year old with sharpie-tattoos selling me his crushed up ADD medication (had been up for 3 days at that point) and started trying to prove it in Coq. I'm not exactly sure what all the bullshit I wrote exactly PROVED, but I DID manage to get it to extract to Haskell and, well, it doesn't crash. I, however, did crash, and the last few days before the deadline were just a blur of furious futa masturbation and huge screaming matches with my roommate/landlord (mom, whatever). Wound up just submitting the Haskell code and nobody has brought it up, since. The light rail system that the code was for hasn't crashed yet, so I guess everything's hunky dory
