Designed and implemented a robust API using Clean Architecture (strict separation between Domain, Application, and Infrastructure layers) while applying SOLID principles, ensuring highly maintainable and testable code for Next.js and Nest.js. Developed a complex JWT-based authentication and authorization system with multiple role hierarchies (SUPER_ADMIN, ADMIN, TEACHER, STUDENT). Implemented custom Guards and Decorators in NestJS to protect endpoints and enforce immutable business rules. Built modern, responsive, and accessible user interfaces with native Dark Mode support. Applied the Smart/Dumb Components design pattern to decouple state management from presentation logic. Optimized UX and software design patterns by implementing a global notification system (Toasts) using the Facade Pattern. Designed a "Flash Toast" system powered by localStorage to persist state feedback across asynchronous redirects. Utilized advanced AI assistants (Gemini and Claude) to accelerate feature delivery, automate boilerplate generation, and optimize complex logic within the educational platform's architecture.

Responsible for creating endpoints integrated with the front end, such as the assignment of patients to nurses in Canada. Led the refactoring of the Nursing Assignment module using Clean Architecture principles with Angular 19 Signals for state management. Designed and implemented drag-and-drop functionality for patient assignment using Angular CDK. Developed and maintained a shared UI component library (chr-lib) used across multiple applications. Implemented full-stack features including REST API endpoints, database migrations, and frontend integration for a shift management system. Implemented feature flag-controlled rollouts enabling gradual release of architectural changes. Leveraged Augment Code via Model Context Protocol (MCP) to efficiently navigate the large-scale healthcare codebase, accelerate the refactoring of the Nursing Assignment module, and maintain strict code quality standards.

Led the development team, providing guidance on technical decisions, supervising code development and implementation. Contributed to the development of applications utilized by thousands of users, including notable clients like Toyota, leveraging Node.js and Angular technologies. Migrated from obsolete technology to modern solutions using Angular and JointJS to improve the user experience. Handled various requests using lazy loading to improve performance and enhance the user experience.

Developed an innovative tool empowering customers of various banks to customize the appearance and layout of their web app from scratch. Managed a data volume exceeding one million users utilizing SQL Server. Managed 20+ successful production deployments, ensuring high-quality standards were met through meticulous testing and deployment processes utilizing Azure DevOps and IIS. Supported the QA team by executing test cases and furthered automation efforts by creating C# and Selenium-based automation tests.

Collaborated on micro frontend architectures, integrating multiple projects with diverse technologies like Angular and AngularJS. Utilized Scala and MongoDB in the backend to efficiently store client information. Proposed and implemented new technology integrations, leading to a 20% increase in system performance. Developed automation tests using Cucumber and Java, and created new APIs with Spring Boot.

Developed frontend applications, resulting in the creation of intuitive user interfaces and optimized user experiences. Collaborated with clients during the development process, ensuring a 95% satisfaction rate by confirming creative proposals and implementing best practices in design and functionality. Optimized existing systems, conducting regular updates, bug fixes, and performance enhancements to ensure consistent and optimal functionality.

Developed new modules in Drupal tailored to meet the specific requirements of the client. Added localization to support 3 different languages. Actively participated in code reviews and provided valuable feedback, resulting in a 50% improvement in code quality and adherence to industry standards.
