• Build and maintain a design system that ensures consistency, accessibility (WCAG compliance), and alignment between design and development.
• Define and enforce frontend testing strategies (unit, integration, and E2E) using tools like Jest, Cypress, and React Testing Library.

• Implement frontend observability practices including real user monitoring, performance tracking, and error logging (e.g., Sentry, Datadog).

• Design, develop, and maintain robust, scalable, and high-performance applications.

• Implement trunk-based development practices to enable continuous integration and rapid delivery.
• Develop clean, maintainable, and testable code following SOLID principles and software design best practices.
• Ensure high levels of unit test coverage, test-driven development (TDD), and behavior-driven development (BDD).
• Actively contribute to hands-on coding, code reviews, and refactoring to maintain high engineering standards.

Engineering Excellence & Best Practices

• Drive the adoption of modern engineering ways of working, including Agile, DevOps, and CI/CD.
• Advocate for automated testing, infrastructure as code, and continuous monitoring to enhance software reliability.
• Apply Behavior-Driven Development (BDD), Test-Driven Development (TDD), and unit testing to ensure code quality and functionality.
• Conduct thorough code reviews, ensuring adherence to best practices in readability, performance, and security.
• Implement and enforce secure coding practices, performing vulnerability assessments and ensuring compliance with security standards.
• Collaborate effectively in agile environments, embracing DevOps principles and fostering a culture of continuous delivery and improvement.

Technical Leadership & Collaboration

• Partner with architects, product owners, and cross-functional teams to design scalable and distributed systems.
• Mentor junior engineers and foster a culture of engineering excellence and continuous learning.
• Collaborate closely with DevOps teams to optimize deployments, observability, and production resilience.
• Lead technical discussions, contribute to design documentation, and provide guidance on modern software architectures.
