• Ensure role-based access, multi-tenant awareness, and secure data flows across front and back layers.
• Create responsive designs with accessibility and cross-device compatibility in mind.
• Implement real-time interactions and logs (WebSocket/Event streaming).
• Write unit/integration tests across the stack; perform debugging and performance tuning.
• Participate in CI/CD pipeline integration and deployment via Docker/Kubernetes with DevOps.

Required Qualifications

• 3–5 years of experience as a Full-Stack Developer.
• Strong command of JavaScript/TypeScript with frameworks like React.js, Next.js, or Vue.js.
• Backend proficiency in Node.js, Python, or Go—building scalable APIs and services.
• Experience with PostgreSQL, MongoDB, or equivalent databases.
• Proficient in containerization (Docker) and working within cloud-native CI/CD environments.
• Understanding of modular frontend/backend architecture and microservices.
• Familiarity with authentication, RBAC, and multi-tenant SaaS design patterns.
