This project involved developing a full-featured E-commerce website tailored to the pharmaceutical industry.

Registered users can participate in sales programs and promotions to access the best pricing and offers available.
🚀 Key Features

⚠️ Challenge
The client struggled with outdated manual order processes that were both time-consuming and error-prone, particularly for bulk orders from their dealer network.

- Custom workflows for different dealer types (pharmacy, hospital, etc.)

- Dealer satisfaction improved due to ease of use and transparency
- Set the foundation for the client’s long-term digital transformation in the pharmaceutical sales ecosystem

Industry: Automotive
Tech Stack: Angular, NodeJS, Redis, Elasticsearch, PostgreSQL, ODATA, Kubernetes (Microservices)
Platform: Web & Mobile
Project Duration: 24 months
🔍 Description
The “Development of Software for Buying and Selling Car on Website and Mobile” project aimed to create a complete automotive marketplace solution for both desktop and mobile users. The platform empowers individuals and car dealerships to list, buy, sell, appraise, and finance vehicles—all in one unified system.

Since the used car market in Vietnam is fragmented and largely offline, creating a trusted, all-in-one solution that was fast, responsive, and mobile-optimized required deep architectural planning.
Maintaining performance during auction surges, building APIs that could serve both web and mobile, and securing financial transaction workflows added additional layers of complexity.
💡 SEA-Solutions’ Solution
SEA-Solutions addressed the challenge with a cloud-native microservices architecture, ensuring each module (auction, finance, listing, chat) operated independently yet cohesively. Highlights included:
- Redis caching for real-time auction and inventory updates
- Elasticsearch for lightning-fast search and recommendation
- ODATA-compliant APIs for structured, cross-platform data exchange
- Kubernetes-based scaling for future-proof growth
- UI/UX tailored for both Web (Angular) and planned mobile app integration (via RESTful APIs)
The 24-month development cycle was divided into agile sprints with rigorous QA and UAT processes involving client feedback at each major milestone.
✅ Result
- Increased lead-to-sale conversion rate by 40% within 6 months
- Seamless user adoption on both desktop and mobile platforms
- Strong technical foundation to expand into insurance, after-sales services, and dealer-specific dashboards
- Helped position Car Vivu as a leading digital player in Vietnam’s automotive market
