Weeks from PRD to MVP

1

Product Hunt launched

Challenge

This classic bootstrap hustle demanded a pitch-ready MVP in just four weeks with no in-house designer: a Chrome-extension cart, a conversion-focused landing page, and a patented search, all primed for angel funding.

Solution

Hired as the Lead Product Designer, I partnered with the Founding team to define the PRD, architect core UX flows, and craft polished UI, branding, and pitch assets, delivering the MVP on time and securing Buyzooka’s business goals.

About Buyzooka

Luxembourg, France

Founded in 2020

Pre-Seed Stage

50+ early adopters

Buyzooka is a Chrome extension shopping cart that connects shoppers to 1.5M+ independent Shopify stores. Its mission is to let users shop across sites and check out in one cart with a single click.

Process

4 Weeks MVP Process

Within the 4 week super sprint, I synced closely with CPO and the Engineer to make sure each of the features and deliverables were developed, tested and QA all at the same time as in lock in back to to back ensure we can ship the MVP on time.

User Pain Points

Top Cross-Site Online
Shopping Frictions

Based on Buyzooka’s user insights and Baymard Institute research, these were the top three pain points the MVP aimed to solve.

Persona

Who We Serve

Buyzooka’s target audience mainly focus on female millennials who love online shopping, indie stores, and embrace “Bobo” (bourgeois‑bohème) style.

User Flow Development

Chrome Shopping Bag Extension Flow

Pre-Install Flow

Post-Install Flow

Based on the user data that Buyzooka provided, I analyzed and complied them into the user journey map to identify the design solutions that I can create for Buyzooka.

Solution

Conversion-First 
Landing Page

Built with a clear onboarding UX writing, this page targets a 1.5–2 % visitor-to-install rate at launch. Post-launch, I advised A/B testing CTAs and download prompts to boost conversions.

Elevate Buyzooka’s
Brand Experience

Branded Extension Tab

I revamped Buyzooka’s Chrome tab by applying its pink-to-purple gradient and shopping bag motif to ensure instant brand recall and a cohesive visual anchor in the user’s browser.

MVP Search Interface

Collaborating with Engineering, I led the design of our internal Shopify-store search page: a modern image-grid layout with live auto-search results that scales across 1.5M+ indie shops.

Chrome Extension MVP

The Cross-Site Shopping Extension

In rapid sprints, I built a scalable MVP UI component library and brand design for Buyzooka. Embedding UX best practices that power a truly cross-site shopping experience.

Testimony

Kind words

Rosie proposed different ideas based on her research with a theoretical basis to try to find the best solution for our product. It was a very good experience working with Rosie. Her fast understanding of our product/business and high productivity makes the project move smoothly.

Key Learning

Design in Agility

I loved diving into Buyzooka’s world. It taught me firsthand the power of agility in a startup. To fuel their indie-shop mission, I shipped rapid, razor-sharp designs that even made our Product Hunt debut. This experience showed me that working with clients goes beyond one-off project delivery. It's about co-creating products and embracing their mission together.
