170 USD Binance Parser
C#The parser had to fetch recent announcements on Binance as fast as it was really possible and rationally utilize the given resources (IPs that were provided by an IPS) to minimize gaps between the requests. Then it would trigger by some word or combination of them in the announcement and react.

49 USD Binance P2P Parser
C#The parser had to fetch the orders list from Binance P2P and present them in a newly generated Google Sheets spreadsheet.
-
291 USD Csgo Parser
C#The task was to create a multi-component parser app that parsed many csgo marketplaces at once and uploaded given data to a MongoDB base in a unified way (ie polymorphic). In the end, we had a DB with a bunch of data from different sources that could be processed without additional treatment by some other bot or human.
Also, one of the components had to generate all the items and their variations, which should exist in the game, and fill the DB with them by parsing csgo's vdf files.

Boots for CS.Money
Проект реализована полностью, чёткое понимание задачи, проблем с коммуникацией не было. Не однократно были крупные корректировки в проекте, всё воспринималось адекватно, работа велась постоянно. Инициативный человек, быстро понимает что к чему. Так же в течении месяца фикс багов.

Preparation of BOT
A great developer: he was always in communication, available to explain the nuances and the principle of his (and not only his) code, optimized the complex code associated with websockets. One of the few on freelancer who doesn’t miss a week for various reasons and doesn’t feed with promises and hopes. I strongly recommend cooperation.
