I’m Harsh Saini, a Software Developer at Cars24 and an IIT (BHU) Varanasi graduate, passionate about building scalable and impactful software systems. I specialize in full-stack development using React, Node.js, and Spring Boot, and have hands-on experience designing microservices architectures with tools like Kafka, Docker, and Keycloak. I enjoy solving complex engineering problems and crafting systems that balance performance, reliability, and clean design. My recent projects include an AI-powered fitness application built on a distributed microservices architecture and several real-time full-stack applications that improved user experience and scalability. I’m continuously exploring how AI and modern backend design can shape the next generation of software. On Topmate, I love sharing knowledge, helping others grow in development and architecture, and collaborating on projects that push the limits of innovation
