Dani Weidner Open to Staff roles

Staff product designer / Enterprise B2B SaaS / 13+ years

Staff product designer for enterprise B2B platforms.

I lead design on complex, multi-team work from customer research through launch, including a platform migration that moved 50 customer accounts with no breaking changes reported, and the layout, navigation, and handoff standards the product is now built to.

Clickable prototype

Roles and permissions admin console

Invite someone and set their class at the door, assign a role per folder, see exactly what an external partner can reach, then transfer ownership or remove access. Fictional workspace and people.

Selected work

Enterprise B2B SaaS, anonymized. Each case leads with the decisions I made and what they cost.

01PlatformLead designerShipped

Rebuilding a platform with every customer still on it

Four aging flows sequenced into six phases, a new builder proven against the old one, and a migration customers never had to touch.

Result
0 breaking changes reported across 50 migrated accounts
Result
2× usability rating over the legacy builder, from 7 customer raters

02FeatureResearch lead and designerShipped

Creating and editing links at scale

Research across three user groups cut a feature nobody needed and put error recovery at the center of the flow.

Decision
Up to 10,000 records per file, every row validated
Scope
14 participants across three user groups

03FeatureLead designerShipped

A/B testing for people who run experiments for a living

Seventeen acceptance criteria, a real holdout in place of a buggy workaround, and a metrics issue caught in a live customer session before release.

Decision
Up to 20 variants, with the interface adapting at each count
Decision
2 of 3 customers preferred campaign-level settings, which set the default

04PlatformAuthorIn use product-wide

Setting the conventions a whole product runs on

Layout, navigation, and handoff standards every team builds to, lifecycle gates built from a handoff audit, and one demand picture for the roadmap.

Result
Layout, navigation, and handoff standards adopted product-wide
Decision
3 lifecycle gates, built from an audit of 5 handoff failure patterns

05AILead designerConcept design

Designing an AI agent that’s honest about what it doesn’t know

Confidence tiers, explainability, and failure states worked out with ML engineers, plus how I use AI in my own practice.

Beyond my own projects

The parts of the job that keep working when I’m not in the room.

Design and engineering

Designin’ With Dani

The biweekly design and engineering sync I’ve kept going at every company since 2020, where in-flight work gets reviewed while it can still change.

People

Coaching and mentorship

Mentor to 2 designers, and coached 10+ designers, PMs, and EMs on the product lifecycle gates I authored.

Systems

Design system stewardship

Specs for new components, and the handoff standard every ticket is written to.

AI in practice

How I use AI day to day

Claude to code 340 logged product requests into themes, Figma Make to prototype, and Claude Code to build this site. More
