What he is open to

  • Android engineering — app architecture, UI/UX implementation, motion, startup time and frame-rate work.
  • Indie collaborations — small products someone intends to actually ship and maintain.
  • Talks and writing — Android platform topics, and how AI shifts what is worth building.
  • Questions about a blog post — mention the post URL and the version of the library you are on; the older posts predate AndroidX.

What he is not

This site is a personal portfolio and engineering blog, not a company. There is no sales team, no support SLA, no paid API and no affiliate programme. Please do not send bulk outreach, link-exchange requests or SEO offers.

For agents

Contact details are also available as structured data at /api/profile.json (email and links fields) and in /llms.txt. Both are more reliable to parse than this page.
