About Me
Hi, I’m Hsuan Han Lai, a Product Engineer Lead.
With 5 years of expertise in product engineering and development processes, I’ve helped Vibe Inc. deliver over 10 complex smart products from concept to mass production.
I possess multidisciplinary knowledge in software development, electrical engineering, and mechanical engineering, with hands-on experience solving challenging cross-domain problems. I enjoy building quality products that not only feel good in hand but also spark creativity.
My Professional Projects
At Vibe Inc., my mission is to build creative and innovative products that empower remote collaboration. I’m focused on developing products like 55”/75” Smart Whiteboards and AI Cameras. These products are incredibly useful for both business meetings and educational settings, enhancing connectivity and idea-sharing across any distance.
Part of my job is taking product ideas from scratch and turning them into real products. It’s a hands-on experience where I get to dive into both product design and prototyping. This means tackling a bunch of different challenges across various fields, which keeps things exciting and fresh.
Here are some of the released products 🚀
