•Managed application state using Angular's dependency injection system to facilitate separation of concerns and maintainability in a container/presentational component architecture, ensuring efficient data flow and code organization
•Implemented lazy-loading techniques in Angular single-page application (SPA) to enhance user experience by drastically reducing initial load times and packet sizes, resulting in a faster and more responsive web application
•Reorganized Angular codebase by structuring it into discrete single-component Angular modules, streamlining code maintainability, enhancing reusability, and enabling more efficient development and testing processes
•Composed declarative, reactive data streams leveraging the RxJS library to handle complex asynchronous data fetching and state transformations using the observer pattern
•Developed a backend server-side application using Node.js framework NestJS, harnessing NestJS’s powerful dependency injection system, decorators, and module-based architecture, to create scalable, efficient RESTful API endpoints that retrieve resources and handle business logic demands of both the client application and API users
•Utilized TypeORM as an abstraction to the data layer to seamlessly define and manage complex relationships between entities within a PostgreSQL database, ensuring data integrity and optimizing query performance
•Integrated Orkes workflow orchestration into feature architectures to accelerate development speed and reduce complexity of creating simple microservices to perform isolated tasks or communicate between different services asynchronously and robustly
•Authored detailed technical specifications for new features, providing a structured framework to guide development priorities and comprehensively documenting key architectural design decisions
