About this gig
Are you looking for advanced AI solutions that go beyond simple ChatGPT wrappers?
I am a Data Scientist specialized in Large Language Models (LLMs), AI agents, and end-to-end NLP pipelines. My expertise covers both foundation models and custom architectures, ensuring that every solution is powerful, scalable, and production-ready.
What I can do for you:
- Custom LLM fine-tuning for domain-specific tasks
- Text classification & sentiment analysis on reviews, documents, and customer feedback
- Summarization, text generation, and grammar correction with Transformers
- Named Entity Recognition (NER) and key information extraction
- OCR + NLP pipelines: invoices, receipts, scanned docs, passports, IDs
- Conversational AI & intelligent chatbots with memory and API integration
- Advanced AI agents with LangChain / LlamaIndex connected to databases and external APIs
With proven experience in business process automation, computer vision, and predictive modeling, I design solutions that are not only accurate but also robust and practical for real-world deployment.
Whether you need a lightweight text classifier or a full AI pipeline with OCR + LLM + MLOps, I can do all this!
