Devashish Roy Chowdhury

I am a full-stack developer experienced in building and deploying scalable web applications using React.js, Next.js, Node.js and MySQL. I focus on secure user management, performant API design, and responsive, user-centered front-end experiences.

In internships across startups and technology firms, I improved UI/UX, ensured cross-browser compatibility, and implemented authentication and role-based access controls. I have hands-on experience integrating payment gateways and real-time features using WebSocket/Socket.io.

My projects include marketplace platforms with Stripe integration, a real-time booking system protecting patient data with RBAC, and a chat application using JWT and Socket.io that increased engagement by 30%. I also designed efficient MySQL schemas and API structures for content-heavy applications.

I bring a strong toolkit spanning frontend (React, Next, Tailwind), backend (Node, Java, MySQL), AI/APIs (OpenAI, Gemini), and DevOps (AWS, CI/CD, Git). I enjoy applying generative AI and LLM integrations to product problems and iterating quickly in agile teams.
