✨ My name is Miłosz and I'm an Information Technology student at Warsaw University of Life Sciences (SGGW).

🎯 I'm passionate about programming, data analysis, backend development, and DevOps.

A curated list of my recent software development projects – covering APIs, full-stack applications, and data science pipelines. Each one emphasizes clean architecture, good practices, and maintainability.

REST API built with FastAPI, PostgreSQL, and SQLAlchemy ORM, supporting JWT-based user authentication and full CRUD operations on posts.

• ✅ Unit tests with pytest
• 🧬 DB migrations via Alembic
• 🐳 Dockerized & containerized
• 🔁 CI/CD with GitHub Actions

📦 Deployed on a local Ubuntu Server (VM).

Recipe-sharing app with:

• 🍳 Flask REST API with SQLite and SQLAlchemy
• ⚛️ React frontend
• 🔐 JWT-based authentication
• 🧂 CRUD for recipes, ingredients, and favorites

Aims to offer personalized recipe recommendations in future iterations.

A set of academic web scrapers built with Scrapy and Playwright:

• 🕵️‍♂️ PW Scraper
  Collects structured data from the Warsaw University of Technology:

  • 👨‍🏫 Scientists’ profiles, 🧾 publications, 🏛️ organizational structure
  • 🧠 Smart pipelines with PostgreSQL integration
  • 🪄 Handles JavaScript-rendered pages via Playwright

• 📰 Punktoza Scraper
  Scrapes journal data from punktoza.pl:

  • 🗃️ Stores data in a PostgreSQL database
  • 🤝 Developed collaboratively during academic work

Useful for academic data aggregation, analytics, or research management tools.

🧠 A machine learning pipeline to classify mobile phones into 4 price categories based on specs.

• 🔍 Models: Logistic Regression, LDA, Random Forest, Voting Ensemble (XGBoost, KNN, etc.)
• 📊 Visualizations with SHAP & stats
• 📈 Best Accuracy: 91% (Random Forest)
• 🧪 Fully modular codebase with experiment-ready scripts

📄 Includes a detailed PDF Report (Polish).

Full-stack contact manager built with:

• 🖥️ Frontend: React + Vite + CSS
• ⚙️ Backend: Flask API + SQLAlchemy + SQLite
• 🔄 Full CRUD: create, edit, delete contacts
