I’m a mechanical engineer with hands-on manufacturing experience in process development and optimization. I’ve worked on industrial wet-pulp molding for Nespresso’s compostable capsules, supporting high-precision workflows, line optimization, and material performance testing. I’m passionate about turning real-world problems on the shop floor into robust, scalable solutions. I combine hands-on problem solving with CAD design, prototyping, validation testing, and data-driven process control to improve product quality and reliability in regulated manufacturing environments. I enjoy cross-functional collaboration with suppliers and partners to bring innovative materials and processes from lab to production.
