Vadiraj Kanakagiri

Led backend architecture and hands-on development of Node.js REST services for a central platform supporting multiple domain applications. Designed RabbitMQ-based asynchronous workflows for email delivery and file processing, including reliability features like acknowledgements, retries, dead-lettering, and idempotent consumers. Implemented memory- and performance-focused processing pipelines using Node.js streams, worker threads for compute-heavy transformations, and Redis caching strategies to support high concurrency.

Built and scaled backend microservices and production-ready REST APIs using Node.js with a focus on reliability, maintainable service boundaries, and performance under load. Developed RabbitMQ workflows for asynchronous tasks and ensured robust consumer behavior with retries and dead-letter handling. Improved system stability by investigating memory issues and enhanced scalability through Redis caching and AWS deployment architecture with API Gateway and auto-scaling.

Developed backend REST services and integrated microservices for a platform used across multiple applications. Implemented asynchronous processing pipelines with RabbitMQ and designed file processing using Node.js streams with backpressure to avoid full buffering. Contributed to API reliability and deployment readiness using AWS components such as API Gateway and autoscaling, and supported production troubleshooting through performance and memory monitoring.

Trained in full-stack web development and contributed to feature development under senior engineer guidance. Worked on API integration, debugging, and code maintenance while learning established development practices. Supported ongoing improvements by implementing and verifying changes in the codebase.
