Where I'll be.

6 ahead / 113 behind

I'm Tejas Kumar, a conference speaker and an AI Engineer at IBM. This is everywhere I'm booked and everywhere I've been, on the real dates, with the recording wherever one exists. The empty days are the ones you can still have.

There are gaps in this calendar. Put your conference in one.

I've given 85 recorded talks since 2012, most of them about AI engineering and the web. If a month above looks empty, it is. Tell me the dates and I'll tell you yes or no within a day.

Invite me to speak

Every recorded talk is on here, back to my first one in 2012. The same list, sorted by what I talk about rather than by when, is on the speaking page.
