01· The Challenge

The alert was buried. The AI recommendation wasn't trusted.

"How might we help an engineer notice, trust, and act on the alert that matters—before it becomes a $1M problem—without asking the user to hand judgment to a system they've never seen be wrong?"

02· The Research: Where Trust Already Breaks

16 in-depth user interviews synthesized into persona, journey map, and insights.

Frictions

→ Opportunities

Alert sits three levels deep in the tree, and the AI Update read like a plain column label.

Surface the alert and the recommendation above the table—nothing to dig for.

No visible reasoning—reads as a black box.

Show the pattern match and the incident history behind it, not just a score.

Confirm looks obvious—so people stop checking, even when the AI could be wrong.

The user weighs the evidence first—Override stays as easy as Confirm, and a thumbs vote helps it improve next time.

03· The AI-Powered Workflow: Human-AI Interaction

The AI never acts alone. The user weighs the evidence before deciding—Override stays just as easy as Confirm.

04· Test and Validation: Rounds of Usability Testing, A/B Testing on AI Recommendation, Banner Cards

05 · The Solution: Shipped AI-Powered Design and Scalable Design Systems

I’ve built reusable components and tokens for scalable design systems that AI agents can read and deploy, enabling a seamless, AI-assisted design-to-code workflow in complex, data-heavy industries.

Implement scalable capabilities using a systems-thinking approach, collaborating with developers and data scientists to deliver B2B SaaS solutions for technical professionals in enterprise UX to support $9-figure industrial operations.

Full case studies on the AI recommendation and AI assistant: how I raised CSAT from 53% to 92%, the technical constraints and trade-offs behind each design. Let’s chat live!
