About me.

Hemant Kumar Angajala has been building software professionally since 2020, but his journey into AI started back in 2019 when he got proper training in Machine Learning and Neural Networks at UPX Academy. Since then he's watched the field go from research papers and Kaggle notebooks to something you can actually ship. Agents that hold state. RAG pipelines that don't hallucinate on every third query. Tools people use daily instead of demo once and forget.

These days, Hemant spends most of his time integrating LLMs into real applications. He works with Claude and GPT APIs, builds stateful AI agents using LangChain and LangGraph, and creates conversational interfaces with Rasa and Dialogflow. When he needs to track and debug LLM applications, he turns to Langfuse. For vector search and RAG systems, he's worked with Pinecone, Chroma, and Weaviate. And when projects need custom ML models, he dives into TensorFlow and PyTorch.

On the full-stack side, Hemant is all about Python and FastAPI for backends. It's perfect for integrating AI services. For frontends, he builds with React, Next.js, and TypeScript, focusing on real-time AI interactions and streaming responses. He also builds mobile apps with React Native when projects need to reach users on their phones.

Hemant deploys everything on AWS and Azure with Docker, making sure applications are production-ready with proper error handling, monitoring, and cost optimization. He follows Agile and genuinely likes collaborating with teams. Building intelligent systems is always better with good people around you.

He picks up new frameworks and tools by actually building something small with them, not just reading the docs. That habit started with his AI/ML training at UPX Academy back in 2019, before most of this was mainstream, and it's stuck. He'd rather break something in a side project than in production.

If you need an LLM wired into an existing product, a custom chatbot, semantic search, or a full-stack app where the AI part is more than a marketing bullet point, that's the work Hemant does. Get in touch and describe what you're building. He'll tell you straight if it's a fit.
