Book Some Time

I keep a few slots open every week for collaboration chats, project kickoffs, or quick mentoring sessions. Pick a time that fits your schedule and Calendly will handle the invites automatically.

Calendly powered — but on brand

Let's talk about your next big build.

30-minute slots, timezone-aware, and automatically synced to both of our calendars. No back-and-forth emails required.

Lightning Kickoff

Scope MVPs, audits, or consulting requests.

Pairing Session

Debug tough bugs or architecture questions.

Schedule via Calendly

Availability Snapshot

New slots

Typically weekdays 9am–7pm GMT+8, plus occasional weekend mornings.

  • • Automatic time-zone detection
  • • Google Meet or Zoom links included
  • • Reschedule / cancel links in every email
Still see the Calendly UI when it opens—this setup just keeps the booking flow branded until then.
