AI-FIRST architecture for senior operators
JBoot treats AI as a core architectural capability: PO, PE, Architect, Marketing/Brand, project contracts, local agents, skills, gates, runtime profiles and auditable decisions before implementation.
- Agents with explicit responsibility for product, engineering, architecture and brand.
- Skills and contracts as operational memory, reducing loose inference and rework.
- Stack Fit Gate to choose technology by real scope, not automatic baseline.
- Separation between Identity, Platform, BFFs, workers and internal capabilities.
