Full cycle developers is a different approach. It requires applying engineering discipline to all areas of the life cycle. Full cycle developers evaluate problems from a developer perspective and ask questions like “how can I automate what is needed to operate this system?” and “what self-service tool will enable my partners to answer their questions without needing me to be involved?”. They think and act like an SWE, SDET, and SRE.
