Problem
- Venues are unreliable: captive portals, Wi-Fi drops, strict IT constraints.
- Sessions run on tight timing; downtime is unacceptable.
- Clients needed meaningful insights during sessions—not after.
Solution
- iOS/iPadOS app for live learning + surveys + facilitator controls.
- Node realtime services for low latency engagement and fan-out.
- PHP framework backend for domain workflows + governance.
- Local event server option for venue resilience + sync later.
| Outcome | What changed |
|---|---|
| Live insight | Real-time engagement + comprehension signals during sessions. |
| Better education | Learning loops improved training, staffing decisions, and prototypes. |
| Repeatable delivery | Runbooks + standardized deployments reduced onsite risk. |
| Trustworthy data | Idempotent writes + reconciliation reduced duplicates/partials. |
