• Designed and developed scalable microservices architecture using Node.js/Golang with asynchronous communication patterns
• Implemented message-driven architecture using RabbitMQ for decoupling services and ensuring reliable data processing across distributed

systems

• Worked in Golang microservices for bulk product data ingestion, handling large-scale product info, pricing, and stock updates from

source APIs.

• Ensured high performance in bulk processing pipelines by leveraging Go routines, pagination in data fetch and transformation logic.
• Collaborated on a system that logged the entire cron job lifecycle and enabled real-time observability across Node.js and Golang microservice communication. All logs were stored and visualized in OpenSearch for monitoring and analysis
• Created and configured Docker containers to test flagship products in isolated and secure environments.
• Collaborated with DevOps teams to debug and troubleshoot issues across multiple Kubernetes pods in staging and production environments.

• Worked in configuration and continuous integration implementation in an agile environment to ship features in the shortest time possible.
• Collaborated with cross-functional teams to establish SSH connection and maintain secure data flow between server to server.
• Collaborated with DevOps team and Implemented load balancing for Node.js applications using Nginx and PM2, resulting in increased scalability.
• and availability.
• Optimized and refactored legacy codebase using Node.js, resulting in a 20% reduction in code complexity and improved performance.
• Designed MongoDB schema and worked on complex aggregation queries & indexes using Mongoose to achieve business logic.
• Designed and implemented data models and key-value storage structures in Redis for efficient data retrieval and manipulation.
• Implemented Redis as an in-memory data store and caching solution to significantly reduce memory usage and enhance application performance.
• Utilized the async.parallel function from the async library to efficiently handle parallel execution of multiple asynchronous tasks.
• Worked on Socket.io in Nodejs for real-time chat application and monitoring process count.
• Responsible for creating unit and code design documentation for new features and existing functionalities.

• Enhanced the application’s features, fixed the bugs, and optimized the overall performance and efficiency.
• Designed & implemented PGSQL Functions, views, triggers, complex queries to improve the performance & reduce data redundancy.
• Created Single Page Applications with responsive web application for smart devices & cross browser using Bootstrap 5 and Media queries.
• Created Angular service and integration with RESTful APIs to send GET/POST requests to fetch data from the server.
• Developed and maintained API documentation using Swagger for multiple projects.
• Worked with Express.js for developing RESTful web API’s and middleware configurations using JSON web tokens for authentication.
• Utilized Node Mailer to send order status and tracking information emails to end-users, improved customer communication and satisfaction.
• Worked on lottery-based algorithm using Node.js.
• Worked with React Native for developing mobile applications and implemented push notifications using firebase to enhance user engagement.
• and retention.
• Worked closely with other engineers to design and implement software solutions that met business needs.
• Utilized version control systems like Git to manage source code, facilitating collaboration and version tracking within development teams.

• Conducted manual testing to identify defects and ensure software quality.
• Created detailed test cases and test scripts based on project requirements and design documents.
• Conducted regression testing to verify that new features and changes did not impact existing functionalities.
• Developed comprehensive test plans and strategies to ensure effective software testing.
