Your comment reminds me of something else you touched on, make everyone around you look good to great all the time. Never call anyone out and give tactical advice to all levels. If someone is really into Redis, tell them about some new cool extension module. If someone likes Kafka, show them some new commit that does a cool thing. Go out and seek these things in technologies the customer uses. They think ur on the ball, and they are given something that they can pass on and look even better.
