Backend Engineer

As a Backend Engineer at DataFlow Systems, I was responsible for designing, developing, and optimizing high-performance backend services that processed over 10 million transactions daily. I architected microservices using Node.js and Python, implemented efficient data storage solutions with MongoDB and PostgreSQL, and designed RESTful and GraphQL APIs for client applications. Key accomplishments include implementing a caching layer that reduced database load by 70%, developing a real-time notification system using WebSockets, and creating a comprehensive logging and monitoring infrastructure that improved system reliability and troubleshooting capabilities. I also collaborated with DevOps to establish CI/CD pipelines and containerization strategies using Docker and Kubernetes.
