ParlayBay is a pioneer company in the micro betting industry. I joined it in the very early phase to work on a prototype version of the game. My first challenge was to refactor the code base and fix major bugs. After releasing the product there was a time to set up a proper development process, maintain and improve the product, enlarge our team. I think that it was most challenging and diverse project in my career.

Side projects

Slot Game

Simple slot game example. There are 5 reels on the screen, once player clicks on "Play!", they start to spin. Reels are animating with a backout easing effect. Made with PIXI.js

CODE VISIT

Video course. Vue.js - Creating advanced web applications

This project was created in Polish for the Helion publishing house. Together with the listener I create an advanced vue project - a prototype of an online store.

The course was created because I received a unique offer from the publishing house whose books I was learning from as long as I used Polish sources. I was very excited because I had never done anything like this. However, I knew that I like sharing my knowledge and I could not deliver this course if necessary.

The course received positive feedback and I am happy with it, but working on editing the film is not my thing, therefore I did not create a similar project.

VISIT

Board game platform

I wanted to create a game platform for board games from scratch, where users can choose between different game formats and play together with friends or bots. More technical details are in the project README

CODE VISIT

Another flappy bird

When there was boom for Flappy Bird back in 2013, many clones came out and this is one of them.

It is made with Easeljs over the weekend.

VR Controller

Idea behind this was that in the cardboard there is no controller, so I wanted to create pair of apps. One that displays something for the cardboard, and another one that connects with this applications and acts as an input.

First part of this project is small vr app - flying rocket. The second part is desktop app which can controll the rocket with keyboard.

Long time ago there was innovative technology which popularity was growing really fast. This project was to try out react 0.16v.

In my opinion one of the biggest adventage is that the react api didn't change much till react hooks which was introduced in version 16.8.
