if you are very good, nothing is a must per-se
• applied integration engineering
– you ship production code, not demos.
– you live in enterprise APIs and auth: OAuth 2.0, consent models, scope design, multi workspace tokens. you know the edge cases from scars.
– you make architecture calls under pressure and defend them to a customer’s principal engineers.
• customer technical ownership
– you’ve taken a named enterprise account from first call to live.– you turn vague asks into specs, and push back when the ask is wrong.
– you have built with the language models.
– you have built for the language models, and treat the agent-tool interface as an open research problem.
• taste - finger feel for good developer experience.
• typist - you explain complex ideas clearly under deadline.
• human - you build trust and admit what you don’t know.
