No Phase 2 features until Phase 1 passes all quality gates. Every phase has explicit acceptance criteria. Scope creep is prevented by design.
Get the schema and domain model right before building features. The data model is the foundation everything else builds on.
Every claim traces back to evidence. Skills are validated against official documentation. Decisions are logged in ADRs.
Runbooks, decision logs, and audit trails are first-class citizens — not afterthoughts. Systems are designed to be observable, debuggable, and maintainable.
AI is wired into real systems through approval gates and read-first defaults. Every workflow produces a portable proof-of-work artifact — a README, a screenshot, a recorded session, or a sanitized evidence pack — that a reviewer can act on without seeing the private internals.

Evidence mapped to specific engineering roles:
- Platform Engineering
- SRE / Reliability Engineering
- Data Infrastructure
- Security Engineering
- Full-Stack / Product Engineering
- Technical Support Engineering
Sample ADRs demonstrating technical decision-making:
- ADR-001: Phase-Gated Development
- ADR-002: Idempotent Webhook Handlers
- ADR-003: API-First Surface Design
Core implementations remain in private repositories. This portfolio showcases architecture, decisions, operational artifacts, and proof-pack outputs from the Connected AI Operator practice. Public-safe by design — no client data, credentials, or internal repository contents.
