Hi, I'm Sumedh Kumar

I developed Storage Direct for Dell's PowerProtect Data Manager to improve protection for enterprise storage systems like PowerStore and PowerFlex. The solution enabled automated backups, simplified data restoration, and supported complete disaster recovery. I designed it as a high-performance, multi-threaded application, integrating with existing services and ensuring high availability. Working closely with cross-functional teams, we delivered a reliable, compliant solution that met enterprise SLAs and SLOs.

Skills used: Java, Spring Boot, Elasticsearch, Python, JUnit, Mockito

I led the back-end development of Tecnex, a one-on-one online mentoring platform, while contributing to product design and overall development. I built core modules like Authentication (JWT), Payments, Query Converters, and Mentor Search using a Microservices architecture, and oversaw database design and management with PostgreSQL for optimal performance and scalability. I also handled DevOps tasks, setting up services from a bare-metal Linux environment and later deploying them on Red Hat OpenShift, and implemented CI/CD pipelines with GitHub Actions and Jenkins for smooth integration and delivery.

I developed a scalable, enterprise-grade middleware application for the Royal Bank of Canada, enabling asynchronous and reliable transaction verification across distributed systems. I implemented Apache Kafka–based event streaming to handle over 2 million transactions per day, ensuring high reliability and zero data loss. The middleware efficiently processed high transaction volumes with low latency and integrated seamlessly with existing banking systems. Additionally, I incorporated robust error handling, logging, and monitoring mechanisms to ensure system reliability, maintainability, and operational transparency.
