Order Monitoring Bot

https://github.com/teimurjan/go-els-tg-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

https://www.npmjs.com/package/sync-query-redux
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

https://github.com/teimurjan/react-gistlab
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

https://github.com/teimurjan/go-p2p
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.

Cryptocurrency Monitor Bot

https://github.com/teimurjan/yobit-telegram-bot
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.

Digit Recognizer

https://github.com/teimurjan/digits-recognizer
I was learning image processing and machine learning. To better understand this, I created a web application that recognizes the digits you are writing. As a consecutive step, I created an article describing the whole creation process.

Count Easy

https://github.com/teimurjan/count-easy
The project was created for educational purposes. Its target is to collect data about your spending on public services, visualize this data using a calendar, and verify the bills via a calculator (which now is in development).

Uniform Web Application
