I was engaged in code refactoring, API integration and various functionality, fixing bugs and flaws. I used new libraries like react-tags input,react-calendar, react-select replacement.

The project where I was a mentor. I showed how to implement a project where were a lot of CSV tables and inserted them into projects. Mainly connected with the d3 library.

It was a website dedicated to healthy eating. I integrated the payment system on the site. I built the functionality of the project: modal windows, choose options, animations, forms, getting and displaying data, connecting the cash register. The customer often changed his decisions about the design and I had to redo it.

It is a website to help drug addicted and alcoholics. I made up 60% of the site and dealt with the various functionality on Next.js and REST API on Laravel. The most difficult was to work with the design. The customer wanted to fit everything without hidden menus and it was challenging.

I did additional functionality like sms verification, sending email, application of discounts for different users different discount and etc, for the automation system caffeine for the terminal. The goal was not allow baristas to cheat, when they send the earning money to the email at the end of the day. Implemented completely by myself.
