This is an archive of my pre-AI-assistance portfolio projects (2023-24), showcasing skills I developed through 100% hand-written code.

More project info can be found on the projects’ own readme.

Note: The portfolio-rag-chat, quant-trading-gym and invoice-parse have been migrated to their own repository fully. Also available on project list on new personal website.

Projects

  1. 7_wonders (Python): Reinforcement learning using Gymnasium library. OOP. Only implemented Deep-Q Learning for now.
  2. catan (Python): Object-oriented programming, practical AI programming.
  3. simple_machine_learning_deployments (Python + Dockerfile): Machine Learning Engineering, Airflow, Flask
  4. earth_surface_temperature (Python): Interactive dashboard using Plotly and Streamlit.
  5. 24_plus_solver (Python): This is mainly a toy project for a challenge, made use of advanced Python syntax like generator and overloading.
  6. chat_csv (Python): Chatbot app that allows you to ask questions about your csv or postgresql data.
  7. sentiment_analysis (Python): NLP. Sentiment Analysis. Web-scraping..

Sentiment Analysis, 7 Wonders, Catan, Simple ML Deployments, and Chat CSV are multi-day projects spanning a few days or weeks, the rest are 1-day projects.
