An engineer who has already built the thing you are trying to build.

I am a FAANG engineer, and I have built hundreds of apps — anything from mobile to web to desktop, plus the integrations and infrastructure that hold them together.

That range is the whole point. When someone gets stuck, it is almost never because they are not clever enough. It is because the problem has quietly moved somewhere they cannot see — the app is fine but will not go online, the payment works but the email never arrives, everything runs perfectly except on other people's phones. Having built on every side of those joins means I can usually tell within minutes which one you have hit.

I help with the part that comes after it works, too — with one honest caveat. I am an engineer, not a marketer. But an app nobody can find is the same as an app that does not exist, and a lot of what causes that is technical: search engines being unable to read your pages, no tracking set up, a landing page that never says what the thing does. That part I can fix. Where something is genuinely a marketing question, I will give you my honest read and tell you when you would be better off asking a specialist.

I work the way I would want someone to work with me: in your actual project, on your actual problem, explaining what is happening in plain English as we go. No jargon unless you want it, no assumed knowledge, and no making you feel silly for asking something basic. You should finish a session with a thing that works and a clearer sense of why — not a recording you will never rewatch.
