I build secure, interactive full-stack web applications with React, Node.js, SQL, and AI integrations.

At Fifth Third Bank, I build React and Next.js applications and Node.js APIs, securing high-volume workflows with authentication, sessions, role-based access control, PostgreSQL, and SQLite. I also integrated third-party APIs and AI/LLM services for document processing, increasing accuracy by 94%.

Previously at HCL Tech and Swiggy, I delivered responsive web applications, scalable REST services, intelligent search features, and reliable dashboards using JavaScript, TypeScript, Python, Angular, Vue, React, Next.js, FastAPI, and Flask. I enjoy improving full-stack reliability through testing, debugging, schema design, state management, and legacy-code refactoring.
