Any salesforce developers here? What's your day-t-day life like? And can anyone compare and contrast it with their day-to-day as a full-stack or front-end/back-end engineer?

uuuh, I guess I am? I work under the MuleSoft branch of Salesforce on backend stuff.

my day-to-day is pretty chill most of the time. Daily meetings, Weekly plannings and Retros. My manager is great and colleagues are great. Not everyone on Slack is great, but most people try and the systems and automation is objectively one of the worst I've ever worked with, cause shit just breaks constantly and I never have any idea about when is it going to be fixed, who's going to fix it or if anyone even seen my slack complaint :D

So all in all, pretty standard corporate work.

Most annoying is their requirement for inclusive language, so now from time to time we get ordered to refactor bunch of docs or repos to remove the word "master" and shit like that, but It's to be expected in a corporate where their job is pretending to care about as many people as possible without actually doing so.

You'll be working with a lot of Indian outsourced tech support, but many of them are great.

This sounds like something right up my alley.

My day to day is Salesforce + fullstack lamp and mern.

For salesforce though, a typical day would be:

running reports,
fixing data issues with API's, or user data,
working through project work,
dealing with the bugs and issues that come up
refactoring existing processes to sit within the platform limitations,

And then the next major release hits and you deal with the mess of fixing broken things and finding new solutions to existing enhancements, this one is an uphill battle most of the time.

Then.... you have the scrum stand-ups, adhoc meetings, and then you have the day job for the mern or lamp stacks, which include much of the same but in a different eco system and less problematic.

As @Hazarth said, a lot of outsourced work is with contractors, be wary, 90% of them aren't worth the diamonds you pay them in my experience, and you'll almost be guaranteed to rip out they're sloppy shit and rebuild it anyway, this grinds my gears the most.

The community is meh, but the documentation is usually very thorough, although some features are lacking in the no-code solutions and force you to get really creative or drop down to custom code to handle things properly.

It's certainly not a platform to take lightly, it's a forever moving goal post.
The pay is good, the work is never ending, and it's extremely easy to do things wrong and be slapped with limits.
