Can u describe some of your daily tasks (those who are considered easy and day to day tasks) and then the hardest task you have ever done?

I have read a lot of different experiences and they usual range from; chilling as a cucumber and every now and then a dumpster fire appears and you have to do extra hours to extinguish it but generally speaking it's chill so if possible i would like to know what kind of stuff you guys do on a daily basis.

My daily routine basically consists of answering emails, fixing bugs that aren't that common that only hits like ~1% of the userbase of the application i manage and developing features ranging from such as adding a new workflow on an existing app or just changing a redirection. Hardest thing i have done would be correcting all the data from a client DB based on the rules they gave us, such rules were supposed to be the base of their DB but after closer inspection they didn't even follow their own rules and because of that i had to fix it so they did follow their own rules.
