Project Case Studies and Innovation

Selected Case Studies: Over years of experience combined with the latest technology trends, we have built solutions that directly drive our clients' business advancement. Here we introduce major case studies that demonstrate the breadth of our capabilities.

1. Insurance Business Support Portal Site

Overview: Developed a full-scratch business portal for small insurance companies. For policyholders, we provided a self-service web system that integrates account registration, premium payments, and insurance claims. For administrators, we implemented policyholder management, claims tracking, and reporting functions. This is a core system that achieves both operational efficiency and customer experience (CX) improvement.

Results/Technology:

• Technology: Robust system architecture using Laravel (backend) and React (frontend).
• Integration: Implemented secure integration with Stripe payment API and external authentication services.
• Outcomes: Completely digitized paper-based application processes and significantly improved business processing speed. Maintained 99.8% uptime despite limited staff resources.

2. Multilingual Trading Company Corporate Site

Overview: Built a multilingual corporate site supporting English and Japanese for an internationally active trading company. We adopted a modern architecture that prioritized ease of content management and optimization of display speed and security. We pursued a design that conveys corporate trustworthiness and innovation.

Results/Technology:

• Technology: Next.js (React framework), adopting Contentful and Markdown files as headless CMS.
• Operations: Built high-speed delivery and robust security environment with Cloudflare. Centrally managed image assets with Cloudinary to reduce operational load.
• Outcomes: Achieved a modern, high-performance site while ensuring immediate content updates.

3. Luxury Real Estate Company Site

Overview: Handled web site coding for a luxury real estate company to embody their brand image. Based on existing Squarespace templates, we applied advanced custom CSS and JavaScript to achieve unique designs and functionality beyond template limitations.
