Sifa ID
AlphaProfessional identity on AT Protocol

A dynamic CV. Because so are you.

You already show your work through what you publish, who you collaborate with, and who endorses your skills. Sifa ID gathers your activity from apps across the open web into one central profile that keeps itself current and is yours to keep.

Every kind of work, one profile.

Articles, code, photos, reviews, talks: the things you make already live scattered across the open web. Sifa pulls them into one profile as you publish, from AT Protocol apps and open sources like ORCID, with more on the way. No copying over by hand.

    Backed by people. Provable by anyone.

    Colleagues endorse the skills they've seen you use firsthand. Every endorsement is signed by a real account and stored in the open, so it traces back to a real person, not a number someone inflated.

    The profile is a website too.

    Every Sifa profile doubles as a standalone site at page.sifa.id, generated from the same records. A masthead, a sidebar, a short bio, and a live activity list. Nothing to maintain, nothing to redesign.
