👋 Hi, I'm Rafael!

AI Engineer • Statistician & Data Scientist • Software Developer


📚 About Me

I’m a developer & researcher passionate about building intelligent systems that bridge the gap between theory and real-world applications.
Worked on TimeFlow - AI Time Tracking. My journey started in financial and insurance mathematics, evolved into mathematical engineering,
and culminated in a PhD on Poisson–gamma modeling with dependency in the prior parameter. Worked in an AI projekt with RAG and depeloped Web Applications. My Menu translating App is featured by the Brno Expat Centre as a Useful App.

I combine mathematical rigor with software engineering to craft AI systems that actually work — not just in theory.


🔭 Current Focus

  • AI + Vector Databases — building retrieval-augmented generation (RAG) pipelines
  • Multimodal Knowledge Bases — integrating images + text for better context understanding
  • OpenAI API & LLMs — using large language models for reasoning, summarization, and search
  • Python & TypeScript — developing end-to-end applications from backend logic to web interfaces

🚀 Projects

  • 📷 Multimodal RAG Pipeline — Store and retrieve images + text in a vector database, then reason with Mistral.
  • 📚 Academic Research Tools — Statistical modeling for Poisson–gamma processes.
  • 🤖 Flowise Experiments — Multi-agent AI workflows.

🎯 My Goal

To create AI systems that are:

  1. Grounded in mathematics 🧮
  2. Engineering-ready ⚙️
  3. Human-usable 🤝
