About
I’m a design engineer specialising in naval architecture, with experience in both yacht and product design. I am passionate about the appearance, functionality and manufacturing process of a design.
At NAVALTEK, I am working on the design and development of a 9.95 m motor yacht and a personal watercraft. My responsibilities include concept development, creating general arrangement layouts, producing detailed 3D models, and preparing designs for production. Previous internships at Damen Yachting and Sirena Marine provided me with valuable insight into shipyard operations and the translation of design decisions into construction.
Alongside my work at NAVALTEK, I am a top-rated freelance designer on Upwork, having completed more than ten projects for clients in Europe and North America. Each project has its own requirements for function, assembly, and manufacturing. These have ranged from RC boat components to modular products and visual prototypes.
I mainly use Rhino to develop detailed models with close attention to tolerances, fit, and how parts come together. Depending on the project, I deliver models that are ready for 3D printing, as well as supporting technical drawings and visualisations to help clients and collaborators understand the design before it is produced.
