As a software engineering intern at a payment solutions company, I worked on modularizing a monolithic application to enhance scalability and maintainability. My role involved defining module boundaries, extracting and decoupling modules, and refactoring and testing them. I utilized domain-driven design and modular architecture to improve the application’s structure, gaining valuable experience in software architecture and complex system design.
