A Message from Our Founder

Thank you for choosing to be part of our journey.

Thank you for visiting. I have built a diverse career across UI/UX design, front-end development, web direction, digital marketing, and SaaS product development over more than 20 years since the dawn of the web. Since founding THINK DESIGN, I have leveraged the flexibility and accountability of individual business operations to provide consistent support from planning and design through development, operation, delivery, and ongoing support.

Our company is a technology company with SaaS (Software as a Service) business and AI development at its core, aiming for continuous growth by providing the cutting-edge technologies and expertise cultivated through our own products to external clients as well. Our proprietary SaaS products and AI solutions serve as both our growth engine and the foundation for providing high-value consulting and development services to partner companies. In particular, we leverage practical AI utilization know-how gained from developing the private AI assistant "BY MYSIDE" that comprehensively covers everything from email management to calendar management for corporate digital transformation and operational efficiency.

In recent years, I have actively utilized modern JavaScript frameworks such as React, Vue.js, and Angular, along with Adobe Creative Cloud, Figma, and various AI tools (ChatGPT, Gemini, Claude, GitHub Copilot, Amazon Q, etc.), achieving both development efficiency and quality improvement through AI co-creation. By utilizing AI-powered prompt design and automated workflow construction, I have reduced repetitive tasks and built a system that allows me to focus on more creative proposals and optimization.

The projects I have worked on span a wide range including campaign sites for major companies, e-commerce sites, corporate sites, digital signage, interactive content, smartphone case and uniform design, and social media operation support. In all projects, I emphasize achieving business goals, maximizing user experience, and optimizing SEO and performance, while thoroughly implementing simple and intuitive design.

For me, web development is always a co-creative process centered on "partnership." I consider it my mission to provide robust and intuitive tools and solutions so that clients can focus on their core innovation. Leveraging the technology and practical experience cultivated through our proprietary SaaS business, I aim to provide essential value across design, development, operations, and marketing.

With extensive practical experience and a spirit of inquiry into the latest technologies, I will contribute wholeheartedly to the success of your projects. I am deeply grateful to be chosen as part of your journey.
