Chi sono
Hi, I'm Senthilnathan, a Full Stack Developer specializing in the MERN stack (React, Node.js, MongoDB, Express), focused on AI-powered web apps and SaaS MVPs. I help founders turn ideas into working products: AI-integrated features (LLM tools using OpenAI's API), secure auth, REST APIs, and responsive React frontends. I also fix bugs and boost performance on existing codebases. My focus: clean, secure code and clear communication. Whether it's a quick fix or a full MVP, I aim to ship something that works, on time. Message me with your project happy to discuss scope.
