About 20 hours solid, in a very high pressure deadline, with a lot of money on the table. 1 day beforehand was spent doing research, reading source code, devising strategy. Next day (+ well into the following day) 20 hours solid development in Python and C++ After that it was deployed to 530 servers worldwide and went live immediatly. Functioned perfectly. No bugs. I was exhausted after that, it took me 3-4 days to recover.
