Piyush Ranjan

I’m a software developer with hands-on experience in Python programming, backend development, REST APIs, and modern web technologies. I enjoy building scalable applications, debugging business systems, and quickly learning emerging tools.

In my current role as a Developer, I develop and maintain responsive web application features using React.js, HTML5, CSS3, JavaScript, and Node.js. I integrate APIs, implement authentication flows, support debugging/testing, and collaborate with cross-functional teams in agile sprints—while contributing through code reviews and issue resolution.

I’m especially interested in AI workflows, including Generative AI and RAG-based applications. Through my projects, I’ve built a Retrieval-Augmented Generation (RAG) knowledge assistant using Python, LangChain, vector search, and REST API-based architecture, and I’ve also worked on analytics dashboards with Python, SQL, and Power BI—always aiming to turn complex problems into usable, reliable solutions.
