Ketham Sanjay

I’m a B.Tech Computer Science student who enjoys turning ideas into clean, user-focused web experiences. I care about building systems that feel fast, reliable, and easy to extend as requirements grow.

In my Software Developer Intern experience, I developed and maintained web applications using ReactJS, Node.js, PostgreSQL, and RESTful APIs. I worked with cross-functional teams to design and implement new features, optimize performance, and ensure responsive design.

My projects reflect how I like to ship measurable improvements. For a Blog Website, I used Prisma ORM with MySQL for type-safe operations and reported a 25% reduction in query errors. For “Loop,” I built a LinkedIn-like networking platform with React.js, Node.js, Express.js, and MongoDB—adding connection requests and post sharing, driving 1,500+ new user connections and 800+ shared posts in the first month, and improving server response time by 30% for efficient data retrieval.

I’m also passionate about AI-powered products, especially using LLMs responsibly and practically. With ConfidentAI, I built an AI resume parser and an OpenAI-powered mock interview experience, including personalized improvement feedback, a daily XP streak system, and a progress-tracking profile—while earning recognition through hackathons and relevant certifications.
