Rick Vink ^{Top-Executive}

I’m a Machine Learning Engineer and Instructor with 8+ years of experience building and teaching end-to-end AI systems. I specialize in NLP (LLMs/RAG, LangChain), recommender systems, and practical deep learning. I’ve taught 1,000+ students across 8+ courses and founded AI-Codex, an education and consulting platform focused on in-depth, hands-on ML.

Selected work
- NLP/LLMs: Built LangChain-based text apps (retrieval, summarization, automation).
- Recommenders: Steam game recommendation engine (collaborative filtering, CI/CD).
- ASR: Papiamento speech-to-text (Whisper) with strong dialect performance given limited data.
- Forecasting: Stock time-series with RNN/LSTM.
- RL/Research: AlphaZero-style chess AI with transformer variants.

Tech: Python, PyTorch, TensorFlow, scikit-learn, LangChain, GitHub Actions, React/Node, MongoDB, AWS, OpenStack.
Interests: Generative AI, production ML, education at scale.
