I built ReTech Shop, my bachelor's thesis project, as a complete Android and web platform for selling IT equipment and booking repair services. I developed the Java app, PHP REST API, MySQL database, and web panels for customers, sellers, and administrators.

For my ML Platform project, I trained and compared 19 models across four public datasets, then served them through a Flask REST API deployed on PythonAnywhere. Random Forest reached R=0.91 for startup-profit prediction, and XGBoost forecasting achieved about 19% MAPE compared with about 70% for ARIMA.

As an Assistant Teacher at Logiscool, I helped teach programming and digital skills to children and teenagers, supported them during practical exercises, and explained problems step by step. I’m looking for my first role as a Junior Java, PHP, or Backend Developer.
