Develop and operate complex frontend systems including public-facing platforms and internal B2B/B2E portals.
Integrate seamlessly with backend microservices and AI-powered services via REST/gRPC APIs; handle async flows, error states, retries, and graceful degradation.
Optimize frontend performance for high-traffic environments (bundle size, rendering efficiency, caching strategies, performance budgets).
Implement secure authentication and authorization flows (OAuth2, OIDC, JWT) in collaboration with backend teams.
Establish and enforce frontend coding standards, best practices, and tooling.
Mentor and develop junior frontend engineers through code reviews, pair programming, and technical guidance.
Apply Agile, DevOps, and CI/CD practices including automated testing, monitoring, and continuous delivery.
Contribute to technical design discussions, architecture decisions, and engineering best practices across the Platform teams.
