INTELITY · HOSPITALITY SAAS · 2025

+34%daily active usage, plus 46 FTE hours given back every week

Hotel staff stopped working around the software

They had moved to WhatsApp and paper lists. I audited all eight modules, built the design system first, then rebuilt each one. Daily use came back, the automation gave hours back, and eight modules now ship from one system.

The callDemos reward novelty. Daily use rewards familiarity.

STILL INTELITY · THE NEXUS AI MODULE

One decision from that project, playable.

Hotel managers automate their operations with rules: when something happens, and a condition is true, then do this. Nexus AI is the module where they write them, and it was mine to design.

A visual flow editor with cards demoed beautifully. A structured rules table matched how managers already write procedures on paper. I could not decide from a mockup, so I built both.

Edit a rule. Toggle one off. Switch views. Ask yourself which one you would rather use fifty times a day. That is the whole argument, and it is what shipped.

OPEN PLAY FINDER · CONSUMER MOBILE · 2025

Livein Las Vegas, and the screens went into the seed round

Players know if anyone is on the court before they drive there

Booking was never the problem. I designed six flows mobile first, embedded with the founding team, around the question players actually ask. It shipped, and it helped raise the round.

The callResponsive web would have shipped faster, but finding a court happens on the way there.

WISEPARK · MOBILITY · 2024

Drivers were not avoiding the app over price. They did not trust the spot would be there.

Trust, not priceInterviews and a parking diary found the real barrier, and it was not the one everyone assumed.

Doubt answered earlyThe app resolves the question while you are still driving, not once you arrive.

One direction scrappedMy first brand read as cold in research, so I rebuilt it instead of defending it.

HOW I WORK

Figma to think. Subframe to build.

Wireframes, flows and design systems live in Figma. High fidelity happens in Subframe, where every screen is assembled from real components rather than drawn. On Open Play Finder the founding team reviewed working interfaces every week instead of pictures of them.

The other half is people. I have run a redesign end to end on my own and I have worked embedded in a product team. Both are the job.

Artifact. The cross-team problem board from Intelity. Engineering, design and product pains mapped, grouped and turned into a weekly priority list. Not a process diagram, the actual thing.
