Ashu Kumar

I’m a Software Developer with 4+ years of experience building enterprise web applications with JavaScript, Node.js, Express.js, React.js, MongoDB, and Oracle PL/SQL. I thrive on backend development where clean APIs, reliable authentication, and maintainable code make a real difference.

At Tata Consultancy Services, I designed scalable RESTful APIs and backend services, implementing JWT authentication, middleware, validation, and role-based access control. I integrated enterprise systems and optimized SQL queries, stored procedures, and packages to improve performance and reliability.

I’m equally comfortable in production support—debugging complex issues through structured logging and root cause analysis, and supporting deployments. In Agile Scrum teams, I collaborate closely with Business Analysts, QA, and stakeholders, delivering stable releases with solid code refactoring and optimization.

Now I’m expanding my expertise in AI-powered applications, including chatbot development, LLM integration, prompt engineering, and intelligent workflow automation. I’m also exploring RAG concepts and AI agent architecture while building Node.js-based chatbot experiences and AI-assisted email automation workflows.
