Interactive software for the show floor.
Touchscreens, kiosks, multi-screen shows and the apps behind them. Built in Detroit, white-label for agencies.
What I buildOne developer, start to show day.
NgeosOne is Evol Johnson's software practice. Agencies bring the design and the client, I build the software, load the hardware and support it on the floor. Your brand, your client, and I never contact them.
Booth touchscreens and kiosks
Product explorers, catalogs, spec finders, lead capture with a show report, lobby and retail displays. Offline-capable, content updated remotely. Fixed price, two to three weeks, on hardware I own or yours.
Multi-screen and show control
Synced video walls, presenter-cued stage screens, companion displays and photo stations that share one network. Custom software written for the room, not a player preset.
Video platform and live streaming
Web, TV and mobile players, HLS delivery, live broadcasts from a switcher, and a capture app that publishes from the sideline.
AI agents and retrieval
Voice and chat agents that look things up and hand off, search over video transcripts with hallucination checks, summaries and translation.
Mobile apps
Flutter apps for iOS and Android: event companions, community video, field capture. One codebase, store-ready, offline where it matters.
Backend platform
Java microservices with Kafka and MySQL: devices, media, advertising, events. The same platform runs the kiosks and the video apps.
Built for agencies since 2011
Show-floor software for Mindfield and EWI Worldwide. Enterprise systems at Compuware. Civic technology with the Detroit Public Library. Kiosk and video platforms of my own since 2018.

Evol Johnson
Software architect, Detroit. I started on show-floor interactives in 2011 with iPad and stage work for auto show booths, and have built kiosks, walls, mobile apps and the backends behind them since. One person does the architecture, the build and the support, so nothing is lost between the deck and the floor.
NgeosOne LLC. In person across Michigan, Ohio and the Chicago area; remote anywhere.
