Order Monitoring Bot

I often order something from US online stores like Amazon, eBay, and others. It is not so simple to do that because most of these eCommerce sites cannot send packages to my country. So, like many people, I use a third-party company that helps me with that. It's a good workaround except for one thing—every time I want to know the status of my order, I need to go to the store's website, copy the tracking number, go to the third-party company's website, and check it there.

I decided to make this process simpler by creating a telegram messenger bot that remembers my tracking numbers and then monitors them. If the status is changed, the messenger will notify me immediately. The project is written in Go and is based on clean code and clean architecture principles.

Synchronize Your Redux State with URL Query Parameters

One of the applications I worked with required a feature that was not available in the list of public libraries. I wrote a new library from scratch and open-sourced it.
The library is about an easy way to synchronize URL query parameters and the Redux store.

React Components to Render GitHub Gists and GitLab Snippets

I built a modern marketing website for a NY-based startup. They had a lot of articles about engineering with various code snippets, some of which were created in GitLab that did not allow embedding the content in the browser. As a workaround, I created a library for both GitHub gists and GitLab snippets with a CORS proxy URL parameter.

Peer-to-peer Local File System

As a project for my senior thesis, I created a peer-to-peer network targeting a local network to have a distributed file system inside the companies. It helped me graduate with the highest grade possible.

One of the dozens of projects to save time and digitalize handwork as much as possible. It is a Telegram bot for monitoring the ascents and descents of cryptocurrencies. This analysis tool helped me to understand the market faster.

Uniform Web Application

A Canadian startup that aimed to create an application to collect information about its inhabitants' wishes and analyze them. The application is a questionnaire app with extended functionality like forms' hierarchy and visualization of the data through the charts and pivot tables.

Heartbeat AI Text Emotions Analyzer

Heartbeat is a text analytics platform with the sole mission to understand emotions. This service helps organizations understand people—customers, employees, and patients—in order to improve the human experience.

Investment Platform

The app is meant to make investments with a group of people. It was designed for the youth market to save money for the goals (like journeys) together. When they've reached their set amount, the group is notified of reaching their monetary goals, and they then can go on their trip!
