Can I vibe code Make?

Build a self-hosted webhook routing and execution engine using Node.js, Fastify, Redis, and BullMQ with a React admin panel.

1. DATA MODEL & STORAGE
- Use PostgreSQL with Prisma. Store 'Workflows' (id, name, active, trigger_type, nodes_json, edges_json).
- Store 'Executions' (id, workflow_id, status: pending/success/failed, payload_in, payload_out, error_log, started_at, completed_at).
- Store 'Connections' (id, provider_name, encrypted_credentials_json, updated_at).

2. CORE WORKFLOW ENGINE
- Fastify API endpoint receiving inbound webhooks at `/api/v1/webhooks/:workflowId`.
- Push incoming payloads directly to a BullMQ queue ('workflow-jobs').
- Worker process parses the workflow DAG (Directed Acyclic Graph) sequential or branching step sequence.
- Implement step handlers: HTTP Request (GET/POST/PUT/DELETE with dynamic headers), JSON Transform (JQ-style syntax), Filter (conditional boolean logic), Delay (sleep duration).
- Support step output referencing via template variables (e.g., `{{steps.trigger.payload.order_id}}`).

3. RETRIES AND FAULT TOLERANCE
- Exponential backoff for HTTP failure responses (5xx status codes, rate limit 429).
- Max retry limit set per step (default 3 retries).
- Dead-letter queue for persistently failing executions with alert dispatch to a web hook or email.

4. FRONTEND DASHBOARD (React + Tailwind)
- Table view listing workflows, toggle status (active/inactive), total run count, and last execution status.
- Detailed execution log page displaying dynamic JSON viewer for input/output payloads of every node executed in a run.
- Basic JSON configuration panel to define flow steps manually or via a visually auto-arranged node DAG viewer using React Flow.

5. OUT OF SCOPE
- Complex drag-and-drop node builder canvas for creation (JSON text definition is sufficient).
- Dynamic multi-tenant OAuth flow user interactions (use static API key or bearer token headers in encrypted connections).
