The Challenge
A broadcast studio, a viewer destination, and the people learning to run shows on both.
Handzin was an early-stage live-streaming and virtual events platform whose anchor customers sat in healthcare and wellness. The team needed a host-side product that felt like a broadcast studio, a viewer-side product that felt like a destination, and a customer success motion that translated both for the orgs paying to run real programs on the platform.

01 — Host Product · Mixer
Live Call, Creation, Onboarding.
The host-side product was called Mixer. I designed the live-broadcast call experience, the creation flow that let a host configure a new event before going live, and the onboarding sequence that walked a first-time host into the studio.
Dozens of states across event setup, in-call moderation, and post-event handoff.

Mixer Live Call
Multi-host broadcast UI with moderation, content blocks, and the in-call state machine that handled live events of real scale.
Mixer Creation
The flow that let a host configure a new event end to end before going live. Designed for first-time hosts and repeat producers in the same screens.
Mixer Onboarding
Three-step sequence that walked a host into the studio without a 40-page manual. The product taught itself.
Post-event handoff
The states after a broadcast: recordings, analytics, the second-screen surface hosts handed to their teams.
02 — Viewer Product
Birdseye View and Fullpage Carousel.
The viewer-facing product included a Birdseye View and a Fullpage Carousel. Birdseye View was the grid overview of attendees, rooms, or content blocks, with its own pagination treatment. Fullpage Carousel handled content moments that needed to take over the screen without losing the broadcast context.

03 — Customer Success & Engagement Lead
The customer-success motion was design research with a phone in my hand.
I was named Customer Success and Engagement Lead for a priority customer set in healthcare and pediatric care. Owned demos, onboarding, in-product design questions, and a running list of platform enhancements pulled directly from how those customers actually used the tool.
How I worked
The CEO, the COO, and an engineering team twelve time zones away.
I worked directly with the CEO and COO, both cofounders, and with the engineering team based out of Australia. Time-zone-shifted work, async by default, with weekly anchor calls.
