PIYUSH YADAV

I am a backend Python developer with 5+ years of experience building robust APIs, real-time features, and payment integrations using Django and MySQL. I focus on scalable API architecture and production-ready backend systems.

I specialize in Django, Django REST Framework, Django Channels and asynchronous programming, and I have deep experience integrating LLMs via LangChain, OpenAI, and RAG pipelines. I also work with vector databases such as ChromaDB and FAISS to enable semantic search and retrieval.

My notable work includes real-time customer engagement platforms, collaboration suites, AI chatbots embedded in web apps, and secure payment-enabled auction systems; I have delivered solutions for clients with high concurrency and production demands. I containerize applications with Docker and follow CI/CD practices for reliable deployments.

I bring a pragmatic, security-minded approach to backend design, clear separation of concerns, and a track record of shipping maintainable systems that combine real-time communication, payments, and LLM-driven features. I enjoy working in collaborative teams that prioritize scalable architecture and continuous improvement.
