Ready to add real AI to your product — not just a ChatGPT wrapper?
I integrate large language models directly into your app, workflow, or internal tool — with proper architecture, prompt engineering, and production-ready code.
What I build:
🤖 AI assistants & chatbots — custom personas, memory, context management 🧠 AI agents — function calling, tool use, multi-step reasoning (LangChain / LlamaIndex) ✍️ Content generation pipelines — automated writing, summarization, classification 📊 Data analytics — extract insights from unstructured text, reports, documents 🔄 Multi-model setups — route between GPT-4o, Claude, Gemini based on task & cost
Models I work with: OpenAI GPT-4o · Anthropic Claude · Google Gemini · Llama · Mistral
Built with: Python · LangChain · LlamaIndex · FastAPI
