## About

I'm a Python Developer / GenAI Developer specialising in backend engineering and AI\-powered applications, currently building enterprise\-scale systems at Cognizant\. My day\-to\-day involves designing and shipping production\-grade APIs with FastAPI, architecting RAG pipelines using LangChain and LlamaIndex, and integrating LLMs into real\-world workflows via Azure OpenAI along with the Backend development\. I care deeply about clean code, system performance, and building things that actually work at scale\. What I've shipped recently: → An enterprise AI chatbot serving 100K\+ users — built on a full RAG pipeline with pgvector semantic search, SQL tool integration, and grounded responses using organisational knowledge → A full\-stack career development platform \(FastAPI \+ Angular\) with skill\-gap analysis, personalised learning paths, and RBAC — including query optimisations that cut response times by 30% → A Human\-in\-the\-Loop support agent using LangGraph agentic workflows with human approval gates for sensitive actions Familiar with the deployment of the applications as well\. My core stack: Python · FastAPI · LangChain · LangGraph · Azure OpenAI · PostgreSQL · pgvector · Docker · AWS I'm passionate about the intersection of backend engineering and generative AI — specifically agentic workflows, RAG systems, and LLM evaluation\. Always open to connecting with engineers working on similar problems\. 📌 Portfolio: my\-portfolio\-bhm8\.vercel\.app 📧 kattaphanindra2@gmail\.com
