Add subtle open-to-opportunities hiring signal

[andrewmcodes]

Summary

The site should signal openness to high-quality work without explicitly stating job seeking.

Problem

• There is currently little directional signal for recruiters, founders, or collaborators

Proposed changes

• Add a small section or callout with:
  • problems I like solving
  • types of teams or products I enjoy
  • optional contact path

Acceptance criteria

• Language stays understated
• The page better supports inbound professional opportunities
• This does not make the homepage feel like a generic resume site
