Hi, I’m Nithya Kala Rajendran. I’m a Full Stack Developer with expertise in MERN, MEAN, and JAMstack. I translate business requirements into technical solutions with a customer-focused mindset, delivering impactful results by blending innovation and efficiency. I enjoy building reusable, responsive UI components and crafting robust backend services that scale. On the frontend, I work with React, Next.js, Vite, Tailwind CSS, Material UI, and TypeScript. On the backend, I’ve built APIs with Node.js, Express, NestJS, Python (Django REST), GraphQL, and event-driven systems with Kafka. I’m comfortable deploying to AWS and Google Cloud, containerizing with Docker, and setting up CI/CD pipelines. I’ve mentored junior engineers, led architecture decisions, and collaborated closely with designers, stakeholders, and clients in fast-paced environments.
