“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.”
