I'm not sure if it is a dev experience, but definitely boosted my morale.

In 2014, my company (in India) sent me to attend a conference in Boston. The conference was about big data.

When I came back, I wrote a blog post about Apache Spark in my company's blog. Because of the blog, my name got mentioned in a prominent newspaper's article about Apache Spark.

PS: That is my only blog post till date
