“They were amused by this
inhouse product and
were happy they don't
have to wait for other
teams for
deployments. Just a
button click and the code
was in production and
there colleagues in US
could test it. So deployer
helped in moving the
code quickly. They
worked over weekends
still deploying there code
and continued shipping.”
