## Product first. Engineering in service of it.

3.5 years taking ideas through design, code, app-store review, and production. And a conviction that software which ships and stops moving is already dead.

## Ask this site

A small live demo: ask anything about me or my work, answered from my own notes.

It is a real retrieval agent over this site's own notes, not a canned FAQ. Agents can call it directly:

```
POST https://saifsiddiqui.in/api/ask
Content-Type: application/json

{"question": "Has Saif built anything 0 to 1?"}
```

The response is a Server-Sent Events stream: one event per retrieval and
tool step, then the answer with citations back to pages on this site.

## Built in the open
