I will build ai agent and rag prototypes with python and API integrations
Jun C.
About this gig
Need an AI agent or RAG prototype that works with your existing data and APIs? I build practical AI integrations with Python, LangChain/LangGraph, vector databases, and REST APIs.
My Basic package covers one clearly scoped AI workflow. Standard and Premium packages cover RAG or agent prototypes, database integration, source code, and documentation. I can connect AI models to your app, process documents, use tool calling, and create a testable MVP.
Before starting, I clarify the workflow, input, expected output, API access, and acceptance criteria. I then implement a small milestone, test it, and provide setup notes.
Please contact me if you need a custom workflow, multiple data sources, WhatsApp or CRM integration, or a larger production AI application.

Hi, I'm Jun, an AI application developer working with Java and Python. I build AI agents, RAG assistants, and AI-enabled business tools.
I help clients automate workflows, build private knowledge bases, extract data from PDFs and Excel, integrate APIs, and add AI to existing software. I also review and improve Simplified Chinese websites, apps, and content.
My stack includes Java, Python, LangChain/LangGraph, vector databases, FastAPI, REST APIs, PostgreSQL, Docker, and OpenAI/Claude APIs.
I start with a small, clearly scoped milestone and scale after we agree on the next step.
