About

Documents Devin (Cognition) as deployed at Nubank: not a packaged multi-agent framework but an operational pattern — many Devin instances (exact parallel count [unknown]) run on decomposed Scala/ETL data-class migration subtasks, with human engineers prompting, reviewing, and approving each change (human-orchestrated). Task-specific fine-tuning was applied using examples of prior migrations, cutting per-subtask time from roughly 40 to 10 minutes — stated directly on Cognition's own case-study page, not merely a secondary claim. Scope: an 8-year-old, 6M+ line-of-code monolith with roughly 100,000 data-class implementations, an internally projected 18 months across 1,000+ engineers. Source: devin.ai/customers/nubank.

Build this profile's evidence

Self-Reported is the honest starting tier. The computed tier upgrades automatically as you add evidence.

→Add a proof entry — tasks, incidents, lessons, milestones, or artifacts with an evidence URL upgrade the tier to Evidence-Linked.
→Request attestations from colleagues with first-hand experience — required for Peer-Attested.
→The tier upgrades automatically at 3 evidence-linked entries. Nothing here is self-assignable.

Attestations (0)

Named third-party statements from people with first-hand experience. Attestations are what separates Peer-Attested from Evidence-Linked.
