My Projects/Repositories

Bigger ones

AGH.Train-thesis-project

System for optimizing seat allocation on trains
Bachelor of Science Thesis Project, AGH, 2021

This is so far the biggest non-commercial project I’ve taken part in. It is a configurable system to optimize seat allocation on passenger trains - a use case example would be passenger seating restrictions associated with the COVID-19 pandemic. Another important functionality is optimization of the seat assignment process for efficient use of logistical resources and increased passenger comfort.

Technologies: Kotlin, Ktor, Ktor-OpenAPI-Generator, Kotest, Mockk, JWT, RAPTOR, Jackson, Gradle

PizzaCostCalculator

Handy Android app which helps to make an optimal decision when choosing pizza size and shape.

Project focused on high code quality and proper coding and Android architecture practices. Much code written with TDD, high coverage levels. Unit tests, integration tests, e2e tests. CI/CD made with Bitrise. SonarQube and CodeCov for metrics.
I wanted this project be the one without any deadlines. It was supposed to answer the question: “If I had unlimited amount of time, how would the code look like then?”

Technologies: Kotlin, Room, JUnit, Mockito, Espresso, Gradle, Bitrise, SonarQube, CodeCov

Smaller ones

MyDinner

Recipe management Android app.

Initially started in Java and legacy, later converted to modern Kotlin Fragments, Navigation component and MVVM Android architecture. The goal was to learn how to write Android apps.

Technologies: Android, Kotlin, Gradle, Fuel, Gson

PostgreSQL-Classes

Database exercises of PostgreSQL and PL/pgSQL.

Although it’s not a project, this repository is a valuable source of knowledge still helpful in my everyday programmer life. Even after years I use it as a straightforward reference showing usage of queries or functions.

PlatformPythonGame

A simple, yet fully playable platform game made with PyGame.

It was the first project I have ever made. Although it’s mostly just modified tutorial code, I like it as it’s memento of my start with the “real IT world” adventure.

Technologies: Python, PyGame, tilemap
