About

Backend Engineer (MTS-2) @ Oracle | Distributed Systems & High-Performance Java I architect and scale mission-critical cloud infrastructure for Exadata Cloud Service, building the foundational APIs that power global enterprise workloads. My work sits at the intersection of low-latency engineering and distributed system resilience, ensuring that massive data environments remain performant and self-healing. Core Impact at Oracle: - High-Scale Orchestration: Architecting resilient APIs to handle complex lifecycle workflows for enterprise database clusters, consistently maintaining 99.9%+ SLA. - Event-Driven Systems: Engineered robust messaging pipelines using Kafka to process high-volume events, leveraging intelligent automation to reduce manual interventions by 45%. - Performance Engineering: Optimized backend services to achieve <200ms response times, focusing on JVM tuning, efficient thread-pool management, and high-performance caching with Redis. - Cloud Reliability: Significantly improved system stability by automating network route management and implementing zero-downtime credential rotation for 500+ weekly infrastructure updates. Technical Toolkit: Languages: Java (Expert), C++ (Systems/Performance), SQL, Bash. Backend & Infra: Spring Boot, Microservices, Kafka, Redis, gRPC, Hibernate. Cloud & DevOps: OCI, Azure, Kubernetes (K8s), Docker, Terraform, CI/CD. Academic Foundation: - B.Tech in Electronics & Communication Engineering | MNNIT Allahabad (CPI: 9.1) - Ex-Microsoft (Software Engineering Intern) I am driven by the challenge of optimizing p99 tail latency and designing systems that thrive under peak load. I’m always eager to discuss backend architecture, the evolution of cloud-native technologies, or the next breakthrough in distributed systems.
