Hello! I'm Hariom Kumawat, a passionate Freelance Python Developer, Django Developer, Generative AI Engineer, and React.js Developer with 3+ years of professional experience in Web Development, AI, and Backend Engineering.
Since 2024, I've been working as a freelance developer, helping businesses and startups build scalable web applications, AI-powered solutions, and custom software. My expertise includes building production-ready applications using Django, Flask, FastAPI, and DRF, along with modern frontend development using React.js.
I specialize in Generative AI and LLM integration, working extensively with LangChain, OpenAI GPT models, and RAG (Retrieval-Augmented Generation) to create intelligent chatbots and AI-driven solutions. I've successfully developed 40+ REST APIs and implemented vector databases using Pinecone and FAISS for efficient information retrieval.
My cloud expertise includes AWS (EC2, S3, RDS, Lambda), and I have extensive experience with PostgreSQL, MySQL, MongoDB, and version control using Git/GitHub. I follow industry best practices for code quality, testing, and deployment.
Available for freelance projects - I'm always eager to take on new challenges, collaborate with innovative teams, and deliver high-quality solutions. Let's build something amazing together! 🚀
