System Renewal Project of API Applications

Overview

I participated in a project to revamp an existing API system that had become difficult to maintain and extend. The renewal was carried out using Domain-Driven Design (DDD), and I was primarily responsible for redesigning the domain model.

Conducted a detailed analysis of the existing system’s database structure and designed a new model architecture that reflected domain concepts, with improved maintainability and scalability. This design became the foundation of the new system and played a leading role in subsequent design and implementation phases. I also actively contributed to the development of version 1 of the new system, including software architecture design, implementation, and code review—helping to enhance overall project quality.
