AI Engineer | LangChain & LangGraph Developer
Building AI systems trained on domain data with Knowledge Base AI, agentic AI, RAG pipelines, chatbot architectures, and GPT/Ollama model integrations for reliable production workflows.
I build AI-first applications focused on knowledge-based intelligence, agentic AI systems, and production-ready chatbot experiences.
My current focus is training and orchestrating AI on domain data using RAG pipelines, LangChain, and LangGraph to create reliable multi-step reasoning workflows.
I design end-to-end Knowledge Base AI platforms with GPT and Ollama powered models, tool-calling agents, contextual retrieval, and scalable backend services for real-world business use cases.
Production-ready FastAPI platform with JWT access and refresh tokens, email verification, password reset, role-based access control, file and website ingestion, and clean architecture with logging and migrations.
RAG operation for PDF ingestion with graph-based retrieval flow for accurate question answering from uploaded documents.
Question and answer chatbot built with retrieval-augmented generation and tool support for grounded responses.
TypeScript chatbot for LlamaIndex documentation question answering, focused on developer-friendly documentation search.
Documentation question answering chatbot built with LangChain and LangSmith focused workflow.
Additional repositories include a C# eCommerce solution and deep learning dataset resources.
