About Rishabh Rawat

Backend Software Engineer with 3+ years at Cisco Systems, building secure, scalable, and high-performance systems. I specialize in Zero Trust Network Access (ZTNA), backend microservices, and cloud-native architectures using Java, Spring Boot, Kafka, and modern security protocols like JWT, JWE, OIDC, and SAML. I’ve contributed to enterprise security platforms by engineering authentication flows, access control mechanisms, and cloud-to-firewall communication pipelines. My work blends deep system problem-solving with clean architecture, CI/CD automation, and reliability engineering, ensuring security and scalability at production scale. Core Technologies: Java | Spring Boot | Kafka | Redis | PostgreSQL | Docker | REST APIs | JWT/JWE | SAML | OIDC | Git | Jenkins Projects: Developed a production-grade e-commerce backend with distributed services (User, Product, Cart, Order, Inventory, Catalog). Integrated JWT-based authentication, optimistic locking, and Redis caching to deliver a system optimized for both scalability and performance. Competitive Programming: Top 2% on LeetCode (Contest 319 – Rank #322) Top 3% in multiple global contests — driven by a passion for algorithms and system optimization. What I enjoy most: Designing secure and performant backend systems Tackling deep system and performance challenges Collaborating on clean architecture, testing, and CI/CD pipelines Open to connecting with engineers, architects, and teams passionate about scalable backend systems and cloud security solutions.
