I'm Yash Khandelwal, a Senior Full Stack Engineer with 6+ years of production experience delivering end-to-end React and React Native apps across fintech, e-commerce, e-learning, and AI-powered consumer products. I specialize in React.js, TypeScript, and building robust back-end services with Node.js (Express) and Python (FastAPI), backed by PostgreSQL, MongoDB, and modern cloud stacks like AWS, Supabase, and Firebase. Recently, I’ve worked as an independent contractor delivering multiple production mobile and web products, including real-time platforms with Agora RTC, government-job notifications, and multi-agent AI systems. I’m passionate about security, CI/CD, design systems, performance, and mentoring teammates in clean, scalable engineering practices.…I'm Yash Khandelwal, a Senior Full Stack Engineer with 6+ years of production experience delivering end-to-end React and React Native apps across fintech, e-commerce, e-learning, and AI-powered consumer products.
