Bestbuy Bot
Web scraping on BestBuy.com: This project includes 2 parts, the first part is the desktop application with the purpose of simplifying the user’s control over the robot. User can define configurations related to robot. For example, defining targeted categories, defining pricing strategy for each category, and start or stop windows service. Also, the desktop application shows the last submitted operation time. The second part is the windows service which is responsible for extracting required data from the BestBuy website and run the calculation operation on product prices based on predefined pricing strategies. Then the service will update products information on the user’s website using a REST API (windows service acts as a client to that API). Technologies that are used for this project are .Net core v3.1 (LTS) WinForms and worker service.
Web scraping on BestBuy.com
PalWallet API: An API with JWT authentication and refresh token, also creates a bitcoin wallet and ethereum wallet. Since this project is working with cryptocurrencies, the security of API is super important and our task was to provide that security. Also, we configured the server in order to host the application. Technologies that are used for this project are .Net core v3.1 (LTS), AWS server. This project does not have any UI, but there is swagger documentation available.

ML Project
Server-Side of a professional trading analisis tool like "tradingview.com".
It supports many exchanges with its all symbols and many time-frames.
Among the capabilities of this project, I can name: trade book, order book, footprint, heatmap etc ...
For handling the data that streams from exchanges websocket we run many background workers.
We have many WebSocket clients that stream a huge amount of data.
To avoid the accumulation of data they fork data immediately to calculation workers.
In calculation workers first of all we serialize the data then we calculate chart data.
We use MongoDB to store chart data and MySql for user data. For all part we used .Net technologies.
For Web Api we used Asp.Net Core with costume athentication system, with complicated caching system.
