PearZest | Dating App

Led the rapid prototyping of a messaging-free dating app; it was a side project.

The aim was to remove friction by having users decide if they want to meet after a 5-minute call. The app would then find a mutually convenient time and place for the first date.

It was an innovative business model that charged venues, bringing in more customers.

Nileny | Social Entrepreneurship Project in West Africa

Spearheaded a social entrepreneurship project that took a unique concept of jewelry from Mali and redesigned it with the expertise of Swedish designers to create a new range of jewelry for sale throughout Europe.

I undertook all market research, formulated the business plan and brand identity, and built the supply chain from scratch. I engaged and trained female Mali villagers to create the jewelry to achieve this.

Furthermore, I applied Lean principles to secure cost-effective partnerships with designers, photographers, and local artisans. Aside from the social aspect, the project goal was to learn by doing and apply lean startup and bootstrapping principles in a non-IT industry.

Music Production

Wrote and produced a soon-to-be-released first album.

I traveled to West Africa to collaborate with a dozen of local artists, musicians, and producers.
