• Built and maintained backend services using Java (Spring Boot, Hibernate, JPA) to handle Shopify workflows like order syncing, product updates, and fulfillment logic across multiple storefronts.

• Created RESTful and GraphQL APIs with Node.js, enabling seamless data exchange between internal dashboards andembedded Shopify apps used by store managers and fulfillment teams.

• Developed near real-time data pipelines using Apache Spark and Kafka Streams to process high volumes of Shopify events— including order placements, refunds, and inventory changes — for analytics and alerting.

• Worked with MySQL to manage structured data like SKUs, pricing, and order history, and used MongoDB to store flexible, schemaless Shopify meta fields and configurations.

• Designed and developed interactive admin dashboards using React.js, TypeScript, JavaScript, HTML5, and CSS3 — giving business teams real-time visibility into sync statuses, webhook failures, and system metrics.

• Automated key backend workflows with Python scripts on Linux, handling tasks like bulk product imports, monitoring APIhealth, parsing logs, and integrating third-party vendor services.

• Containerized microservices using Docker and deployed them with Helm on AWS EKS, ensuring scalable, resilient rolloutswith blue-green deployment strategies.

• Designed cloud infrastructure on AWS, working with EKS, Lambda, S3, SQS, and CloudWatch to support event-driven automation, scalable data pipelines, and real-time system monitoring. Integrated ELK Stack for log aggregation and analysis.

• Used Terraform and GitLab CI/ CD to automate infrastructure provisioning and deployments, ensuring smooth and consistent release cycles across dev, QA, and production environments.

• Secured APIs and internal tools using Spring Security, OAuth2, and JWT, aligning with multi-tenant RBAC standards to enforce user-level access and data separation.

Contributed to a scalable e-commerce and order management platform for a US-based retail client using Java 11, SpringBoot, and J2EE, developing RESTful microservices and integrating with payment, logistics, and inventory systems.

• Developed Node.js services with Express.js and TypeScript for non-critical features like notifications and real-time updates, improving responsiveness and system performance.

• Created reusable front-end components in React.js, TypeScript, Redux, and Material UI for key modules; migrated legacy JavaScript to TypeScript to enhance maintainability and reduce bugs.

• Implemented JWT-based authentication and RBAC in Java and Node.js services to ensure secure, role-based access across user and internal applications.

• Integrated Apache Kafka for real-time event streaming between order, shipment, and inventory services, enabling faster data synchronization and decoupling service interactions for better scalability.

• Worked with both PostgreSQL and MongoDB, designing efficient schemas, creating indexes, and applying partitioning strategies to handle large volumes of order and customer data with complex query patterns.

• Containerized microservices using Docker and supported cloud deployment to AWS ECS; collaborated with the DevOps team to provision and manage infrastructure using Terraform.

• Built and maintained CI/ CD pipelines using Jenkins and GitHub Actions, incorporating SonarQube for static code analysis, along with ESLint and Prettier for enforcing code quality and formatting standards.

• Wrote unit and integration tests using JUnit, Mockito, Jest, and Super test, maintaining over 90% code coverage across backend services and frontend components.

• Documented RESTful and GraphQL APIs using Swagger/ OpenAPI and supported QA teams with Postman collections, mock data, and API contracts for validation and testing.
