Behind every IHI page, form, and email is one Python engine running on a Google Compute Engine VM at engine.myagencycore.com. No Firebase. No GoHighLevel UI. No third-party dashboards. Just a real backend with a real database.
The Stack
- Python 3.14 + FastAPI for the HTTP layer.
- SQLite for persistence (WAL mode, transactional, real durability).
- Jinja2 templates for all rendered pages.
- Resend for transactional and broadcast email.
- Caddy reverse proxy with auto-renewing Let's Encrypt certificates.
- Google Cloud Storage for backups and asset delivery.
Why This Matters For You
When you submit a property through the IHI Master Intake, the data lands in a real database you can verify. Submissions are timestamped, payloads are persisted as JSON, and every action is recorded in the asset log. No black box. No "the platform might be down."
What Runs Through It
- Funnels (opt-in pages + thank-you pages) for every lead capture.
- Forms with multi-step A/B variants.
- Drip sequences with branching logic.
- Subscriber lists with tagging and segmentation.
- Single landing pages like this Authority Hub.
- Books with multi-chapter readers.
- The blog you are reading right now.
One engine. Every brand. Every surface. That is the architecture.
