Electrical Engineering
Project-based professional services where design authority, owner approval, and multi-discipline coordination determine delivery.
This interactive experience is the shipped product itself — the same application code customers run in production, mounted read-only in your browser over a real sample journey. Not a video, not a mockup: because the demo and the product are one codebase, it can never drift from the real thing.
