Upendra Singh

I am a Senior Full Stack Developer with 7+ years of experience building scalable web and mobile applications. I specialize in backend development and focus on creating robust RESTful APIs and real-time data processing solutions.

I build AI-powered applications using Generative AI, RAG (Retrieval-Augmented Generation), and vector databases like FAISS and Pinecone. I also integrate AI/ML models into production systems to enable intelligent automation and insights.

Across large-scale projects, I develop versioned APIs for multiple front-end applications and design scalable microservices architectures. In my most recent role, I developed full-stack web applications with Python, Django, ReactJS, and TypeScript, optimized REST APIs with Django REST Framework, and integrated real-time analytics using AWS services and containerized deployments.

I’m passionate about delivering high-quality, efficient solutions across all stages of the software development lifecycle—working in Agile teams, using secure authentication (OAuth2.0/JWT), and supporting stability with testing, CI/CD, and monitoring.
