About Proofline

Proofline is a long-term skill portfolio for knowledge workers. It connects to the tools where work happens and builds a source-linked timeline of projects, demonstrated skills, and professional growth.

We believe careers should be evaluated on evidence rather than polished claims. A verified record of real contributions, specific endorsements, and increasing responsibility gives workers a durable reputation—and gives hiring managers and clients a signal they can trust.

Proofline is intentionally designed to compound slowly. The longer you use it, the clearer your trajectory becomes and the harder your track record is to imitate.
