Divyansh Singh

I’m Divyansh Singh, a Full Stack Developer passionate about building impactful and scalable software solutions. Currently pursuing Electronics and Communication Engineering with Mathematics at BITS Pilani, I’ve worked across the stack—developing production-grade RAG pipelines with FastAPI, secure payment systems using Node.js and MongoDB, and mobile apps with Flutter.

I bring experience from internships and freelance projects, where I’ve built real-time data handling systems with Firebase, designed intuitive UIs from Figma, and developed robust backends with Django and GCP Cloud Functions. Beyond projects, I lead as a Sub-Coordinator at Developer’s Society, BITS Goa, managing a 40+ member team and maintaining key campus repositories.
