Ask HN: What competitive advantage you have over others in your field of work?

E.g. Backend developer who knows K8S so they can work much more efficiently with DevOps, mobile developer with a great flair for marketing, etc. Looking for real-world examples!

In my particular case I am reasonably good at backend development, k8s, search + a bit of marketing and it allows me to roll-out non-trivial products on my own quickly. It has served me well so far.
