Experience

Warehouse

I've built a warehouse system for a pool company. They track all stock item arrivals and removals in it. It is split into two parts. One is for warehouse workers, and another is for admins and ordinary users. Each part has a different authentication mechanism. Thanks to this system, they can track each stock item change. They can see who did the change and when it was done.

Ski School

A Ruby on Rails application for Ski school management. I created it in 2014, and it is still being used and running on the latest versions of Ruby and Ruby on Rails. The primary use case is managing clients, ski instructors, and booking skiing lessons.

Todos

https://github.com/mrhead/todos

A simple to-do lists application was created with Ruby on Rails and Hotwire. It is one of my toy projects. It demonstrates how you can make an Ajax-heavy application with almost no JavaScript code. I created the application with server-generated JavaScript responses, but I migrated it to Hotwire shortly after release.

Stimulus Search

https://github.com/mrhead/stimulus-search

Another one of my toy projects. This application demonstrates how to create an autocomplete functionality with Stimulus. The main functionality was extracted from a real-world project I worked on.
