About Kwstas

Kwstas T.Status: Offline
AI Application Engineer FastAPI + RAG +Document Extraction Specialist
Chios, Greece - 6:47 am local time
I'm an AI Application Engineer specializing in building production-ready RAG systems, AI agents, and intelligent backends.
I recently built two production-grade AI projects: a multi-restaurant AI chatbot with LangGraph agents, parallel vector search, JWT authentication, and streaming responses (FastAPI, ChromaDB, Google Gemini, Next.js), and a Greek regional economic research assistant with custom scoring formulas and multi-tool LangGraph agent.
What I can build for you:

AI chatbots and RAG systems that answer questions from your documents or data
FastAPI backends with AI agent integration (OpenAI, Gemini, Claude)
LangGraph multi-step agents with memory and streaming
Data extraction pipelines from PDF, HTML, and structured data
