02 · How it works

A portfolio built like an engineering file.

Proofolio isn’t a social network. There are no likes, no followers and no feeds — just structured evidence of what you can do, and full control over who sees it.

01
Document the project
Problem, existing solutions, your approach, engineering application, implementation and results — in a consistent structure reviewers understand.
02
Attach the evidence
Upload CAD drawings, simulation outputs, test data, reports, videos and certificates. Files are stored privately.
03
Control who sees it
Make each project public, private, shared with selected people, or visible as a summary with evidence on request.
