About

I don’t just write code — I build systems that solve real-world problems at scale. I’m a Software Engineer specializing in full-stack and cross-platform development, with hands-on experience in building real-time applications, scalable backend systems, and AI-driven solutions. I work across technologies like React, Node.js, Flutter, Firebase, and FastAPI to turn ideas into production-ready products. In my current role, I’ve built and optimized full-stack applications used for real-time interaction and healthcare services, focusing on performance, reliability, and user experience. Previously at CRIS (Indian Railways), I developed an intelligent chatbot with 85%+ accuracy and improved system response time by 30%. I’ve also engineered B2B mobile apps adopted by enterprise clients and automated systems that reduced manual effort by 40%. I’m now looking to work on high-impact products where I can contribute to scalable systems, solve complex engineering challenges, and grow as a product-focused engineer. I’m especially interested in roles that combine system design, backend engineering, and real-world problem solving.
