Love code. You take ideas as an input and give beautiful, working, product as an output. Frameworks and languages are just tools for you. You use ones that are the best fit for the job.
You know how to build systems. You have built some on your previous experience and maintained them. You scaled systems. You are interested in DevOps. You love back end and know how to create RESTful APIs.
You can communicate. Communication is the key. You can communicate well in English. You can communicate with other team members and customers. We embrace everyone to be in the front line, to know why and for who you are building software.
