Krishna Kumar

I am an entry-level software developer with hands-on experience building backend-focused web applications using Node.js, Express, and MongoDB. I have developed RESTful APIs, authentication systems, and database-driven features for real-world projects.

I built and maintained a full-stack e-commerce platform with JWT-based authentication, role-based access, Razorpay integration, and 20+ RESTful endpoints, owning features from development to deployment. I optimized MongoDB queries for performance and followed structured SDLC practices throughout the project lifecycle.

I also developed an AI-powered credit underwriting web app using Python, Streamlit, and transformer-based models to predict loan approval probability and generate PDF summary reports. I used AI tools to experiment and accelerate development while gaining academic exposure to AI/ML concepts.

I am comfortable working in remote, collaborative environments, familiar with Git and Postman, and hold certifications in Full Stack Web Development (MERN) and Web Application Security. I am eager to contribute to production-ready software systems and grow within a development team.
