This service manages loans and calculates interest and notifies users via Amazon SES for overdue loans.• Took part in the migration process of backend services from JavaScript to Typescript. TypeScript allows for easier error detection and improves code maintainability. Frontend code was also migrated later on.• Implemented the unit test infrastructure for microservices using Jest, ensuring comprehensive code coverage and reliable software quality assurance.• Developed RESTful APIs for the CAPAY System. Utilized Nest.js for server-side rendering and routing, Prisma for database interactions, and implemented Controllers and DTOs to ensure clean and structured API design.• Designed and implemented new dynamic reporting module for CAPAY. Module translates json to rawSQL through self written SQL query builder.• Refactor various SQL queries using CTE to improve the system performance. This was done as there were bottlenecks causing load issues in the system. Show less
