I will build nlp, sentiment analysis and rag applications

Hi, I'm Arman, with 5+ years of experience in NLP and AI/Machine Learning and 3+ years building RAG and LLM applications. I help businesses, startups, and researchers turn unstructured text into valuable insights, automation, and intelligent AI solutions that reduce manual work, uncover opportunities, and accelerate decision-making.

Services include:

1. Text Classification & Sentiment Analysis
2. Named Entity Recognition (NER)
3. Topic Modeling & Summarization
4. Chatbot & Conversational AI Development
5. LLM Applications & Text Generation
6. Question Answering Systems
7. Information Extraction & Document Intelligence
8. Retrieval-Augmented Generation (RAG)
9. LLM Fine-tuning for Specific Domains

Technologies:

• Hugging Face Transformers (BERT, RoBERTa, DistilBERT, T5)
• GPT-4, Llama & Mistral apps
• LangChain & LlamaIndex for RAG Applications
• OpenRouter & LLM APIs
• Vector Databases (Pinecone, Weaviate, FAISS, Chroma)
• BERTopic & Advanced Topic Modeling

With expertise in both traditional NLP techniques and modern LLM-powered systems, I build solutions that help extract insights, automate repetitive tasks, and turn text data into a competitive advantage.
