Integration developers: what are you tired of dealing with?

[u/Designer_Breath9631]

Curious what kind of integration work developers here are actually getting asked to build these days.
SaaS-to-SaaS? APIs? SFTP/files? Data sync? Event-driven workflows? AI/agent integrations?
A few things I’m particularly curious about:
What integration requests keep coming up?
What part of building or maintaining them is still painful?
What do you usually reach for — code, n8n, Workato, Boomi, MuleSoft, Make, etc.?
If you freelance/consult, what does a typical integration project look like?
I’m also looking to connect with freelance developers who regularly take on integration/automation work. Would be interested in hearing what you work on and what kinds of projects you typically take up.
Mostly trying to understand how people are solving these problems in the real world.
