This is just a small subset of what I worked with. The tools outlined here are mostly production-ready and widely adopted ones, but I also love experimental stuff that aims to improve performance of high-level languages.
- Focused on modern JS/TS backends, automation, and ML applications
- TensorFlow Certified Developer (verify)
- Strong foundation in algorithms and data structures from competitive programming (C++)
- 2nd place nationwide at NetOI (Ukrainian Internet Olympiad in Informatics) in 2025
- Multiple other IT Olympiad wins at regional and international levels
- Creator of multiple Telegram automation bots
- Research (for now only high school though):
- Converting Number Systems Using a Graphical Interface (2023)
- Detecting Fake News Using Artificial Intelligence (2024)
Started coding at the age of six and have been passionate about computer science ever since.
Over the years, I’ve explored everything from low-level programming in C and C++ to fullstack JavaScript/TypeScript development and applied machine learning with Python.
Today, I focus primarily on modern JS/TS ecosystems. I'm still maintaining my strong background in Python and machine learning.
I also maintain and develop several useful Telegram bots and automation tools to simplify everyday workflows.
