Developing Angular 21 applications with modern architectures, reusable components, accessibility support, and high-fidelity Figma-to-code implementation. Using contract-first OpenAPI integration with autogenerated clients and models to improve type safety and backend synchronization. Building policy-tracking dashboards with Signals and NgRx, leveraging ClaudeCode and MCP for development automation and test generation, and optimizing Nx monorepo CI/CD workflows with affected commands to reduce build and testing cycles by 60%.

Developed and maintained Angular applications from versions 15 through 20. Completed framework migrations to improve system stability, created reusable and accessible components, integrated REST APIs and authentication systems built in Java, and contributed to testing with Jasmine and Karma. Improved code quality and security through Sonar and Fortify analysis.

Developed web and mobile e-commerce platforms using Angular, React, Ionic, Node.js, NestJS, and WordPress. Designed a dual-database architecture using PostgreSQL and MongoDB, implemented cron jobs for data cleaning and synchronization, built REST APIs and WebSocket-based real-time communication, and integrated Redis for caching and performance optimization. Implemented JWT and OAuth2 authentication, integrated third-party APIs, and supported deployment and backend management on AWS using EC2, RDS, and S3.
