Angular and Frontend Development

• 6+ years of hands‑on experience in frontend development, with strong expertise in Angular.
• Strong understanding of Angular fundamentals, including components, directives, pipes, dependency injection, routing, forms, lifecycle hooks, and change detection.
• Experience developing scalable applications using Angular modules and/or standalone components, depending on the Angular version and project architecture.
• Strong proficiency in TypeScript, JavaScript (ES6+), HTML5, CSS3, and modern frontend development practices.
• Good understanding of responsive design, cross-browser compatibility, accessibility, and web standards.
• Strong practical knowledge of RxJS, including Observables, operators, error handling, subscriptions, and memory‑leak prevention.
• Experience implementing state management using NgRx, including actions, reducers, selectors, effects, and store-based application architecture.
• Understanding of asynchronous programming, event‑driven UI behavior, and efficient API data handling.
• Experience with Angular Material and reusable UI component libraries.
• Proficiency in CSS, SCSS/SASS or LESS, Flexbox, CSS Grid, and responsive layout techniques.
• Experience with Bootstrap or equivalent responsive UI frameworks.
• Strong attention to UI consistency, usability, accessibility, and design implementation accuracy.
• Solid understanding of RESTful APIs, HTTP methods, status codes, authentication, and error handling.
• Experience with Git‑based version control, branching strategies, and collaborative code reviews.
• Familiarity with npm, package management, Angular CLI, and modern frontend build tools.
• Experience writing unit and integration tests using Jasmine, Karma, or equivalent testing frameworks.
• Understanding of browser developer tools, debugging, performance profiling, and frontend troubleshooting.

Key Responsibilities

• Design, develop, and maintain scalable, responsive, and user‑friendly web applications using Angular (v20+).
• Build reusable components, directives, pipes, services, and feature modules following established frontend architecture and coding standards.
• Develop maintainable, modular, and testable code using TypeScript, JavaScript (ES6+), HTML5, and CSS3.
• Implement application state management using NgRx and leverage RxJS for reactive programming and asynchronous data flows.
• Integrate frontend applications with RESTful APIs and collaborate with backend teams to define API contracts and handle errors, loading states, and data validation.
• Build consistent, accessible, and responsive interfaces using Angular Material, Bootstrap, and modern CSS techniques.
• Optimize application performance through lazy loading, code splitting, change detection optimization, efficient rendering, and bundle‑size reduction.
• Apply appropriate Angular compilation and build optimizations, including AOT compilation and production build configurations.
• Write and maintain unit, integration, and component tests using Jasmine, Karma, and other relevant testing tools.
• Participate in code reviews, enforce coding standards, identify technical debt, and recommend improvements to frontend architecture.
• Troubleshoot complex UI issues, investigate production defects, and implement reliable, long‑term solutions.
• Collaborate with product managers, UX/UI designers, backend engineers, QA teams, and other stakeholders in an Agile/Scrum environment.
• Contribute to technical design discussions, effort estimation, sprint planning, and continuous delivery practices.
• Stay up to date with Angular releases, frontend engineering best practices, and emerging web technologies.
• Independently own complex frontend features from requirement analysis and technical design through implementation, testing, and release.
• Translate business requirements and UX designs into maintainable and scalable technical solutions.
• Evaluate alternative implementation approaches and make informed decisions around architecture, performance, and maintainability.
• Identify performance bottlenecks, resolve complex defects, and proactively improve application reliability.
• Mentor junior developers, share technical knowledge, and promote coding standards and best practices.
• Communicate technical risks, dependencies, estimates, and delivery progress clearly to stakeholders.
• Demonstrate accountability, adaptability, curiosity, and a continuous learning mindset.
