You've got 3–7 years in. Your resume says you know TypeScript; it doesn't show you designed the service, owns the on-call rotation, and mentored two juniors through it. We read what you've actually built and give you a profile that shows the difference — before your next job switch.
OAuth in one click. We read your public repos — commits, reviews, pull requests. Nothing private, ever.
Our AI maps your activity to the open devskills taxonomy — 5 layers, 40+ skills. Peers can attest to what code alone can't show.
Flip on your public profile. Link it anywhere. Methodology is open so anyone can verify how your levels were assigned.
The taxonomy behind Arbor is public. Every level descriptor, every behavioral statement, every weighting rule is open for inspection. You should be able to see exactly how your credential was produced.
Three orthogonal axes make growth legible: an L3-across-the-board engineer knows the path to L4 runs through judgment and ownership — not learning another language.
View full taxonomy →Code quality, testing, systems thinking, operational awareness, AI-assisted development. Skills every engineer needs regardless of stack.
Languages, frameworks, infrastructure, databases. Evidence comes from what you actually ship, not what's on your resume.
Communication, mentorship, product thinking, organizational influence. Only peer attestation can assess these — code alone can't.
Public GitHub artifacts, peer attestation, and self-reported context. Each fills gaps the others can't reach.
Peers affirm specific behaviors they've directly observed — drawn from level descriptors. No stack-ranking, no comparative framing.
Peer attestation can lift your public level but never lower it. This is intentional — peer feedback should expand credentials, not weaponize them.
Real-time engagement events are instant. Public-profile level changes run on a weekly cadence so your credential doesn't shift overnight from one new attestation.
