Repositories do not prove understanding
Anyone can fork a repo or follow a tutorial. Employers cannot tell if you wrote the code, understood the architecture, or just copied it. Portfolios lack proof of depth.
Depth verification
Peer sessions test understanding, not just output. Your SCI score reflects genuine comprehension.
Portfolio enhancement
Link your Lemma passport alongside your GitHub. Give employers both the work and the proof behind it.
Skill-level detail
Each verified skill shows granular detail: tier, confidence, session count, and growth trajectory.
2xmore technical interviews
Developers who pair portfolios with verified skills get more meaningful interview conversations.
Frequently asked questions
GitHub shows what you built. Lemma proves how deeply you understand the skills behind the work.
