Key Responsibilities :
- Architect and oversee frontend systems using React.js (upto latest), Next.js (upto latest), and TypeScript across large-scale projects.
- Define and evolve frontend architecture patterns (micro-frontends, modular monorepos, islands / adaptive hydration).
- Lead performance engineering with SSR / SSG / ISR, CDN strategies, lazy loading, INP optimization, and edge rendering.
- Establish and maintain reusable component libraries, design systems (e.g. shadcn / ui), and theming strategies.
- Implement secure coding practices (CSP, XSS / CSRF prevention, OAuth2 / JWT flows).
- Collaborate cross-functionally with DevOps, backend, and infrastructure teams to streamline CI / CD and DevSecOps pipelines.
- Guide adoption of code quality standards, including linting, typing (Zod, tRPC), automated testing (unit, integration, E2E with Playwright).
- Lead technical ceremonies : architecture reviews, RFC discussions, performance audits, and roadmap planning.
- Mentor engineers across levels, from onboarding juniors to elevating seniors to leads.
- Handle complex debugging, production fire-fighting, and systemic reliability issues across devices and browsers.
- Contribute to internal tooling, documentation, and frontend platformization initiatives.
