• Develop and maintain reusable Angular components using TypeScript, RxJS, and SCSS for responsive, high-performance web interfaces.
• Collaborate with cross-functional teams, including backend developers, UX designers, and product owners, to translate functional and business requirements into technical deliverables.
• Write and maintain unit tests using Jasmine and Karma, along with integration tests and Taiko automation scripts for comprehensive coverage and UI stability.
• Monitor and manage GoCD CI/CD pipelines, troubleshoot and rerun failed builds, and coordinate with DevOps to maintain deployment integrity.
• Conduct peer code reviews and provide detailed feedback, ensuring compliance with coding standards including linting and static code analysis for security and quality (for example, SonarQube).
• Integrate RESTful APIs and manage complex application state using NgRx and RxJS.
• Participate in Agile ceremonies including daily standups, sprint planning, estimation, and retrospectives.
• Mentor junior developers through code walkthroughs, Angular best practices, and support for career development.
