Key Responsibilities :

1️⃣ Full Stack Development (Frontend & Backend)

✅ Backend (Java, Spring Boot, Microservices)

Develop RESTful APIs and microservices using Spring Boot, Hibernate, and JPA.

Implement database interactions with SQL (Oracle, PostgreSQL, MySQL) and NoSQL (MongoDB, Redis).

Optimize backend performance, ensure scalability and fault tolerance.

Implement authentication, authorization (OAuth2, JWT, SAML, LDAP).

✅ Frontend (React.js / Angular / Vue.js)

Develop user-friendly, responsive UI components using modern JavaScript frameworks like Angular and Ionic.

Integrate UI components with REST APIs and WebSockets for real-time data updates.

Optimize frontend performance (lazy loading, caching, code splitting).

2️⃣ API & Integration Development

✅ Develop RESTful and GraphQL APIs for frontend and third-party integrations.

✅ Implement asynchronous messaging using Kafka, RabbitMQ, or ActiveMQ.
