Judge sign-in

Your preferred or professional name. It appears on your public judge card and is the default for certificates.

Any email you check — that's where invites go.

Choose a recognizable photo — JPEG, PNG or WebP, max 10 MB. It is required for your judge card and resized in your browser before upload. You can replace it later in Profile.

One line shown on your card, e.g. "Lead Engineer · 10 yrs · AI security". Up to 500 characters. You can edit this later in your profile.

Longer details — publications, talks, judging experience. Up to 5000 characters. You can edit this later in your profile.

First is your LinkedIn (required). Add up to 4 more — Twitter/X, personal site, blog, etc. You can edit this later in your profile.

Paste your username or any link — we pull your avatar automatically (same live check as participants).

Pick one or more — you can be several. Whether you're approved for the current hackathon is up to the organizers.

Pick as many as you like — your application lands in each one’s pool, and organizers decide separately.
