Professional Experience & Key Responsibilities:

Backend Developer – Enterprise Project

• Migrated a modular monolithic application to microservices using the Strangler Fig pattern with API Gateway and Saga Orchestration for distributed transaction consistency

• Implemented Redis caching selectively for product catalog, user profiles/roles, and rate-limiting, improving performance and reducing database load

• Leveraged Kafka for asynchronous side-events like order confirmations, notifications, audit logs, and analytics, ensuring decoupling for non-critical workflows

• Secured microservices with JWT-based authentication and authorization at the API Gateway and service level using JWKS validation

• Integrated AWS SDK for S3 (storage of product images and invoices) and SES (transactional emails), improving scalability of external dependencies

• Performed thorough API testing using Postman, ensuring accurate responses and smooth integration with internal and external services

• Tools and Technologies Used: Java, Spring Boot, Redis, Kafka, AWS SDK, MySQL, Feign, API Gateway, JWT, Prometheus, Grafana, ELK

Backend Developer – Internal Project

• Developed and maintained backend modules (Claims, User Management, Reporting) using Spring Boot, ensuring clean modular design and scalability

• Built RESTful APIs for claim lifecycle management (submission → validation → approval/rejection → reporting), with proper validation, pagination, and exception handling

• Integrated Redis caching for frequently accessed data (claim statuses, reports), reducing database load and improving response times

• Applied JWT authentication and role-based access control (RBAC) to secure APIs for agents, adjusters, and admins

• Implemented Kafka-based messaging for real-time claim status notifications, ensuring instant updates for stakeholders

• Configured Log4j2 and integrated with Splunk for centralized structured logging, monitoring, and audit trails

• Tools and Technologies Used: Java, Spring Boot, REST APIs, MySQL, Redis, Kafka, OAuth2, Log4j2, Splunk

Personal Project – E-Commerce Application (Full Stack Developer)

• Built a scalable platform using ReactJS and Spring Boot with a microservices architecture

• Implemented JWT authentication, Redux for state management, and Axios for API communication

• Enhanced performance with lazy loading and improved fault tolerance using Resilience4j

• Integrated payment gateway for payments and SMTP for secure user registration and password resets

• Tools and Technologies Used: Java, Spring Boot, Spring Data JPA, Spring Security, Microservice Architecture, ReactJS, Redux

Education:

• Rajiv Gandhi University of Knowledge and Technologies – Basar (2018–2022)
