Portfolio

Covid Tracker App

Spring, Java, HTML, CSS, JS

App created during the Covid-19 pandemic that shows the number of daily infections worldwide. It is a table listing countries in alphabetical order. I used Spring to write it and fetched data from the internet via the GitHub COVID-19 dataset API. Feel free to visit GitHub and check out the code.

App with GUI

Library

JavaFX, PostgresSQL

A simple library model with all basic operations such as adding a book to the library, editing its properties, and removing it from the collection. It’s a basic database model — I plan to expand it with patrons who can borrow and return their favorite titles.

App with GUI

Calculator

React

This is my first practical application built with the React library. I wrote a basic calculator that supports all essential mathematical operations: addition, subtraction, multiplication, and division. It also handles longer expressions like 3*2+9-1.

App with GUI

HR Program

Spring, React, Full stack

My first successful attempt at writing a working full‑stack application connected to a database. Spring handles the program logic (backend), while React is responsible for the website appearance. The application also uses a PostgreSQL database. It’s a simple-to-use app for adding employees, editing their data, and removing them from the company.

App with GUI

Snake Game

React

Does anyone still remember the game where a snake ate small objects, grew, and avoided obstacles? Those were memories from older phones. With React, I brought those memories back by creating a clone of that game in a short time. The rules are the same as the timeless original: steer the snake so it doesn’t hit the walls while growing as large as possible.

App with GUI

Dining Philosophers Problem: multithreaded app

Scala

A non‑graphical application that uses multithreading to solve a common programming problem. The code is entirely written in Scala. The dining philosophers problem is explained in detail on the YouTube link and on GitHub — just click the icon to learn more.

Console application

Max3Sat

C++

A command‑line application written in C++ that optimizes a solution to the Max3Sat problem. This problem is one of those for which there’s no single great universal algorithm. The program’s goal is to find a solution as close to optimal as possible. The problem itself deals with satisfiability of logical clauses, useful in areas such as logic circuits. For more details, see the YouTube link or GitHub.

Console application

Interests

Programming is not my only hobby. In the summer I often go swimming, which helped me master three basic strokes. I also enjoy cycling, volleyball, and badminton. I'm not fond of winter sports, I usually spend that season indoors.

I also stay busy at home. I'm a big fan of Formula 1 and other motorsports. Recently, I've become interested in technologies related to building and managing websites.

Certificates

During my studies I managed to earn the following Cisco academy certificates. They cover the CCNA 7 course, specifically the first two chapters.

I did so well on the Cisco academy tests that I received congratulatory letters, which are awarded for scores of 75% and above.
