• Ownership of multiple multithreaded microservices built on Spring/Springboot framework for implementing Order Warehouse Management System.• Employed design patterns and scalable backend systems to enhance code quality, reducing post-production issues by 56% and improving the application’s performance by 32%.• Implemented integrations with several marketplaces (including Walmart, Amazon, Paytm, Flipkart, etc..), facilitating seamless data exchange and transactions.• Introduced CI/CD Pipeline to automate code delivery. Implemented Amazon CodePipeline (AWS CodeCommit, AWS CodeBuild, AWS CodeDeploy) that is running live on production reducing deployment effort time by 73%. Led Knowledge Transfer seminars within the organization to scale-up the usage.• Utilized Elasticsearch and Kibana with APM (Application Performance Monitoring) for logging. Enabled comprehensive monitoring and analysis of application performance metrics and log data. Created custom Dashboards on Kibana that provides a live interface for the Board of Directors to visualize company’s profits.• Built Event Driven applications using Amazon EventBridge reducing order creation time by 62%. Following the Push-Based Mechanism (listening to Amazon SQS) where Orders are pushed to our system and created in record-breaking < 2500ms• Led initiatives to integrate Apache Kafka into our systems, harnessing its capabilities for real-time data processing, messaging, and event streaming. Integrated Kafka with our existing legacy system to deliver optimal performance and internal improvements leveraging best practices of topic partitioning.• Implemented Proof of Concept (and led Knowledge Transfer Sessions for all the senior engineers) for Amazon Services like SQS, SNS, and S3 that is running live for multiple clients with maximum efficiency. • Incorporated Apache Airflow, adept at designing, scheduling, and monitoring data pipelines and workflows.

• Utilized Redis cache with RedisTemplate to improve application performance and scalability. Demonstrated ability to design and implement efficient caching strategies, leveraging Redis's in-memory data storage capabilities.• Implemented various business web-based implementations on Restful APIs and Remote Method Invocation (RMI) in the system to facilitate inter-service communications. • Used Hystrix in Springboot Framework to enhance the reliability and resilience of microservices architectures. Integrated circuit breakers, fallback mechanisms to gracefully handle and recover from service failures. • Designed and developed interactive dashboards utilizing MongoDB as the data source, enabling real-time data visualization and analysis.• Designed and implemented Cron job scheduling mechanisms within microservices architecture to automate routine tasks and streamline system operations.

• Developed dynamic and interactive user interfaces using JavaScript within the Struts framework, enabling seamless integration of client-side functionality with server-side logic.• Addressed and resolved urgent issues under pressure, ensuring minimal impact on end-users and business operations. • Implemented authentication and authorization mechanisms using JWT Tokens to secure API endpoints and control access acting as an API gateway using spring framework.
