Subbir A.

I build practical AI-powered applications that help businesses get real value from large language models without the complexity. My focus is on end-to-end AI integration: connecting LLMs to your existing data, tools, and workflows. Whether you need a smart chatbot, a document Q&A system, or an automated pipeline, I design solutions that actually work in production. Here's what I bring to your project: → RAG (Retrieval-Augmented Generation) I design and build systems that let AI answer questions from your own documents, PDFs, databases, or knowledge bases with high accuracy. → LangChain & LLM Orchestration I use LangChain to wire together LLMs, tools, memory, and agents into reliable, multi-step pipelines. → Vector Databases I work with Pinecone, ChromaDB, Weaviate, and FAISS to build fast, scalable semantic search and retrieval systems. → AI API Integration I integrate OpenAI, Anthropic Claude, Gemini, and open-source models (Mistral, LLaMA) into web apps, SaaS tools, and backends via REST APIs. → Embeddings & Semantic Search I build search experiences that understand meaning, not just keywords. I'm honest about what I offer: I specialize in AI integration and application development. I don't do model fine-tuning but for most real-world use cases, you don't need it. Smart prompting, RAG, and well-structured pipelines solve 90% of business problems more efficiently. If you're looking for someone who can take an AI idea from concept to working product, let's talk.
