Optional criterion — significant technical work that advances the field
This optional criterion rewards substantial technical innovation or engineering contribution: novel algorithms, system architecture, security research, infrastructure at scale, or other technical advances with demonstrable effect. It maps to the endorsement guidance on innovation as a founder, senior executive, or employee working on a new digital field or concept.
Two things must be clear from your evidence: your specific role (versus the team's output) and why the contribution matters to the wider field — depth, originality, and external impact, not only internal feature delivery.
