Projects

I have been working professionally since 2017. Below is a list of some personal projects created outside of work in order to develop my skills. I also encourage you to read my profile on GitHub and Codepen.

Diss the World

2017

A social networking site focused on international activity. User entries are distributed via multiple channels. In the default posts are assigned to countries. A system of groups and events was implemented with various access levels. Each entry can have assigned tags, each tag and post is assigned one of three 'emotional values', which can be included in an extensive filter system and sorting. Socket.IO along with Express was used to maintain client communication with the server in real time.

The content of the game is editable from the admin panel (virtual currency packages, weapons, levels, prize counters). The game has been implemented, among others dialogue system, chase system (including hearing and sight of enemies), floor system, push notifications. I also created a fully customizable level generator.

Triangular Arbitrage Bot

2018

Cryptocurrency autotrader using triangular arbitrage technique, supported by CLI. Configurable in every detail (including safety thresholds, level of 'aggressiveness'), with the possibility of creating exceptions, etc. It has many functionalities, e.g. 'round-robin' proxy. It can serve as a normal alarm about reaching price thresholds. For this purpose, I also create a chatbot available here.
