How is everyone else Building Agents

I’ve been building AI agents for sometime now, especially building voice AI agents. I’ve read and watched tonnes of stuff- but they mostly just cover basics.
I have built agents that do over millions of minutes of talking every month- these took me weeks to make them reliable. I have realised that in practise, its much more complex and time taking to build agents – especially with high reliability.

So i wanted to understand what others are doing to build these agents. Got any must-check-out resources or any smart hacks that are working out ?

Would love to hear any thoughts and recommendations
