Olicuero is a student entrepreneurship project developing a bio-based leather material from Tunisian olive pomace, aimed at offering a sustainable alternative to traditional leather. I led marketing and communication for the team: shaping how the product and concept were presented, converting our written report into a clear, visual PowerPoint presentation, and preparing speaking points to pitch the project confidently. My focus was making a technical, sustainability-driven concept easy to understand and compelling to a non-specialist audience.
