Gaurav Bansal
Staff Software Engineer with 8+ years of experience building scalable full-stack systems, developer platforms, and fintech integrations. Currently at Visa Inc., where I architect AI-native developer platforms and developed a Model Context Protocol (MCP) framework that enables LLMs to generate production-ready payment integration code while preventing API hallucinations—reducing merchant onboarding time from 30 days to 3 days.
Strong expertise in Node.js, TypeScript, and Java for backend systems, along with React.js for building developer portals and complex frontend dashboards. Experienced in designing REST APIs, distributed systems, SDK platforms, and secure payment architectures. I actively leverage AI coding tools like ChatGPT and GitHub Copilot to accelerate development, refactor legacy systems, and improve engineering productivity across full-stack applications.
