Hackathon

Created in one week by a team of five during a hackathon, JABU is a service designed to reduce food waste in collective catering environments. Our team reimagined the brand through a holistic approach, from product experience and UX/UI to business model refinement and communication strategy. I led the UX/UI direction and project coordination, bridging product logic, interface design, and business considerations. Our concept for JABU's product and communication strategy won the challenge.

./ Research & Ideation

We began with co-creation workshops, including ideation sessions, card sorting, and “Back to the Future” mapping.
These methods helped align team and client perspectives, highlight user pain points, and outline clear functional priorities.

We redefined JABU’s model around three subscription tiers combining commissions, automation, and optional connected fridges.
The structure made the offer flexible and scalable across institutions.

./ Inventory & Waste Monitoring

./ Inventory & Waste Monitoring

The “Unsold” view allows teams to track collected and uncollected baskets, filter by category, and identify recurring issues, making waste management measurable.

./ Mobile App

Diners can view and order available baskets directly from their canteen, with real-time availability tracking. The goal: make ordering as frictionless and intuitive as any e-commerce flow.

./ Outcome

./ Outcome

In just one week, our team built a functional dashboard prototype for business owners and a mobile app prototype for diners, both focused on real-world usability and data flow. We also developed a complete visual identity system, including communication assets and packaging concepts, ensuring brand coherence across every touchpoint.


Beyond design, we restructured the user experience and proposed new, scalable business models aligned with JABU's client base and long-term growth strategy -> earning first place in the competition and recognition from JABU's leadership team.
