The problem
Courses don't give feedback.
Tutorials don't know your gaps.
YouTube doesn't answer questions.
The people who actually know are out there. They're just not easy to find.
A single artifact employers can actually trust.
Public by default
Your passport is a shareable URL — no login required for viewers. Link it from a CV, email, or LinkedIn in one click.
Tamper-proof evidence
Every session and proof event is append-only. No retroactive edits, no inflated scores — the ledger is immutable.
Lives where you share it
Embed your passport link anywhere. Employers see the full breakdown: sessions, SCI, tier, and peer ratings — all in one place.
Grows with you
SCI is a living score. As you complete sessions and earn endorsements, your passport updates automatically — no renewal needed.
Learn. Prove. Be trusted.
Learn
Book a peer who already built what you want to build. Or drill solo with a tutor that adapts to your gaps – not a syllabus.
Prove
Every session leaves a mark. Ratings, transcripts, working artifacts, peer endorsements. Nothing claimed – all shown.

Skill Credibility Index
A score you earn, and can defend.
Six tiers, one open formula. Every point on your SCI is traceable back to a session, a proof, or a peer. Nothing guessed. Nothing endorsed. Only shown.
Everything you need to earn a credential that means something.
Matched by signal, not by bio
Twelve signals – skills, goals, timezone, reliability – find the peer you actually need.
Two sides of the same community
Find someone who built what you want to build.
Browse practitioners by skill and tier. Book a live session. Get the kind of feedback only someone who's actually been there can give – not a tutorial, not a course, a real person.
- Live sessions with practitioners who built the thing
- Matched by skill, timezone, and reliability
- Every session becomes tamper-proof proof
- Your SCI score rises with each verified session
React Performance
with James K. · SCI 87 · Expert tier
Turn what you know into income and proof.
Teach what you've already built. Every session you run earns LemmaCoins, builds your SCI score, and grows the proof that your skills are real. You learn by teaching. It compounds.
- Assess candidates against verified peer session evidence
- Skill signal piped directly into your pipeline via API
- Webhooks, SDKs, and a developer-grade portal
- Replace unreliable screens with real proof records
Early community
Real people. Real sessions. Real proof.
I was stuck on React hooks for weeks. One 60-minute session with someone who'd built production apps and everything clicked. Can't get that from a course.
I started teaching TypeScript to fund my own learning. Six sessions in, I'm earning LemmaCoins and my own score is climbing. I learn more by teaching than I ever did studying.
The matching is genuinely good. My first session was with someone three levels above me who had done exactly what I was trying to do. Two hours felt like a month of solo study.
