I am a Product Design Engineer specializing in the development of complex electro-mechanical products, transforming ideas into manufacturable, real-world solutions. Since January 2023, I have focused on designing durable, user-centric products for high-traffic and demanding environments, with particular expertise in enclosure design for consumer electronics and IoT devices. My work combines aesthetic industrial design with rigorous engineering principles to create products that are visually appealing, structurally robust, and optimized for manufacturing. I specialize in designing enclosures and housings for both sheet metal fabrication and injection-molded plastics, ensuring sensitive electronics are protected while maintaining an intuitive and refined user experience. This includes close collaboration with RF engineering teams to integrate antennas and wireless components seamlessly into the mechanical design, ensuring optimal signal integrity without compromising structural integrity. I enjoy solving challenging design problems that require a deep understanding of materials, thermal management, PCB design and layout constraints, structural integrity, and efficient assembly. From custom kiosks and handheld devices to RF systems and embedded electronics hardware, I bridge the gap between electronic engineering and physical product design. I work closely with cross-functional teams, including interior designers, to ensure that large-scale installations or interactive kiosks harmonize with their spatial environment and architectural context. My deliverables typically include complete, manufacturing-ready CAD packages with clear documentation to support prototyping, production, and scaling. By incorporating principles of architecture and product design, I ensure that every product-whether a handheld consumer device or a permanent fixture-is engineered for longevity, usability, and real-world performance.
