About Saurabh Kumar

I am a final-year B.Tech Computer Science student at the Indian Institute of Information Technology Gwalior and a Full-Stack Software Developer with a strong focus on backend engineering, scalable system design, and performance optimization.I have hands-on experience building production-ready web applications using the MERN stack, where I’ve worked on everything from designing secure REST APIs and database schemas to developing responsive, high-performance frontends. During my internship at Bluestock Fintech, I led a team of developers to deliver a large-scale IPO web application, taking ownership of architecture decisions, API security, database optimization, and end-to-end feature delivery in a fast-paced startup environment.Beyond traditional full-stack development, I have actively worked on cloud and GenAI-powered systems. My projects include CloudSpend, an AI-driven cloud cost optimization platform that analyzes AWS/Azure billing data, detects anomalies, and provides intelligent cost-saving recommendations using RAG pipelines, LangChain, and Vector Databases. I enjoy building systems that combine real-world data, automation, and intelligent decision-making.I’m equally passionate about problem-solving and competitive programming, which has helped me develop strong fundamentals in DSA, algorithms, and core CS concepts. I’ve achieved the Expert title on Codeforces (1644 peak rating) and maintain an active LeetCode profile (1550+ rating), having solved 500+ problems across multiple platforms.Technically, I’m comfortable working across:Backend: Node.js, Express.js, REST APIs, Authentication & AuthorizationFrontend: React.js, Next.js, Redux Toolkit, SSRDatabases: MongoDB, MySQL, PostgreSQLCloud & DevOps: AWS, Docker, Kubernetes,OpenShift, CI/CD, VercelGenAI: RAG, LangChain, OpenAI APIs, Vector DatabasesI’m always eager to learn, build, and scale impactful products, and I thrive in environments where ownership, problem-solving, and continuous improvement matter. I’m currently open to backend / full-stack software engineering opportunities where I can contribute to challenging systems and grow as an engineer.
