Hi 👋, I'm Rafael

🚀 Python AI Developer | Full Stack Software Engineer | Open to Relocation 🇪🇺🇬🇧

I’m Rafael Arias — a full stack developer with a strong focus on AI and backend automation using Python.
I specialize in designing intelligent systems powered by LLMs, web scraping, and scalable APIs.
My core stack includes: Python, Flask, JavaScript (JS), TypeScript (TS), React, Streamlit, and LangChain.

🧠 AI + Automation with LLMs

Built a PDF question-answering assistant using LangChain, FAISS, and OpenAI.
This tool parses scientific PDFs and allows users to ask questions via a Streamlit interface.
Used chunking, semantic search, and retrieval-augmented generation.

🔍 AI for SEO & Web Scraping

Worked as a Python AI Engineer on an SEO platform that automated content visibility optimization.
Built tools with Django, Redis, BeautifulSoup, and OpenAI for clustering and automation.

💻 Full Stack Development

Strong experience with modern front-end tech (React, TypeScript), and backend frameworks (Flask, Django).
I enjoy building clean, interactive UIs that connect with AI-powered APIs.

🏆 Selected Projects

  • ✅ LLM-Powered PDF Assistant – RAG pipeline for document search (LangChain + Streamlit).
  • ✅ AI SEO Platform – Automated SEO workflows using OpenAI + scraping.
  • ✅ TaskIt – Marketplace for service providers with task bidding and payment flow.
