Can I vibe code HubSpot?

Build a full-stack, developer-focused CRM and Marketing Automation platform in Next.js (App Router), TypeScript, PostgreSQL, and Tailwind CSS, modeled on core HubSpot functionality.

DATA MODEL (Prisma ORM):
- Contact: id, email (unique), firstName, lastName, phone, stage (LEAD, SUBSCRIBER, OPPORTUNITY, CUSTOMER), ownerId, customProperties (JSONB), createdAt, updatedAt.
- Company: id, name, domain (unique), industry, ownerId, customProperties (JSONB).
- Deal: id, name, amount, stage (QUALIFIED, PRESENTATION, CLOSED_WON, CLOSED_LOST), pipelineId, companyId, contactId, closeDate, ownerId.
- Ticket: id, subject, status (NEW, OPEN, WAITING, RESOLVED), priority, contactId, assigneeId.
- Workflow: id, name, triggerType (FORM_SUBMIT, PROPERTY_CHANGE, EVENT), status (DRAFT, ACTIVE), nodes (JSONB execution graph).
- EmailCampaign: id, name, subject, bodyHtml, status (DRAFT, SCHEDULED, SENT), sentCount, openCount, clickCount.
- ActivityLog: id, entityType (CONTACT, DEAL), entityId, type (EMAIL_SENT, STAGE_CHANGE, NOTE, CALL), payload (JSONB), createdAt.

CORE FEATURES TO IMPLEMENT:
1. Contact & Deal Management UI:
   - Dynamic table views for Contacts and Companies with filtering by custom properties and pipeline stages.
   - Kanban board view for Deals with drag-and-drop stage updates that trigger background activity logs.
   - Unified activity timeline UI showing all emails, notes, stage updates, and form submissions for a specific contact.

2. Visual Workflow Execution Engine:
   - React Flow interface to visually build linear conditional automation sequences (e.g., Trigger: Form Submitted -> Delay 1 Hour -> Send Email -> If Clicked, Set Stage to OPPORTUNITY).
   - Server-side execution runner using BullMQ/Redis to process workflow steps asynchronously with delay logic and retry handling.

3. Form Builder & Ingestion Engine:
   - Dynamic form configuration generator (JSON-driven schema).
   - Endpoint `/api/v1/forms/submit` accepting cross-origin POST payloads, creating/updating Contact records using email matching, and triggering configured workflows.

4. Email Campaign & Messaging Engine:
   - Rich text email template editor with variable personalization tags (e.g., {{contact.firstName}}).
   - Integration with Resend API for bulk email sending, tracking webhooks for opens and clicks to update campaign analytics.

OUT OF SCOPE:
- Native social media auto-posting or ad channel syncing.
- Complex multi-currency engine.
- AI conversation agents or credits system.

FAILURE MODES TO HANDLE:
- Race conditions during high-volume form submissions for existing contacts (use upserts on contact email).
- Infinite execution loops in circular workflows (enforce node depth limits and max execution caps per contact).
