It is always difficult to answer this question. I just want to say "I was just doing my job".  If without too much modesty. There was an experience of reworking a non-working microservice into a reliable part of our microservice ecosystem. My experience in the medical domain has made it a habit to keep test coverage at least 85-90 percent.
I have experience in various fields from small startups to creating part of microservices in large projects, there were several large projects related to medicine at the moment, and my current project is in the trade area.
There is nothing special. In general, as experience has shown, the main thing is a good team and any tasks or issues will be done.
