    Hey, I’ve been programming for 4 years. At the moment, I mostly code chatbots. But I also have a lot of experience with scrapping. I can make automation tools for different services with authorization, use proxy, and make anonymous bots for data collection and automation of routine tasks. I am keen on creating user-friendly interfaces. Why me? — You should hire me because I care about your project and I work for the result; — I’m always online and I support already developed projects for as long as necessary; — I like to take non-standard tasks and I learn quickly. My expertise lays in: ► Python 3 ► Selenium WebDriver ► Telegram API ► MongoDB ► MySQL ► Git ► Google Sheets API ► Binance API (and scraping from other crypto-exchanges like Huobi, Gate.io, Kraken, Bitfinex) ► REST API ► HTML5 / CSS3 ► JavaScript ► Regular Expressions I’m from Odesa, Ukraine. My previous experience mostly consists of coding web scrapers and analytics services for e-commerce businesses. I quickly learn, so if your project involves the use of the technologies I am not familiar with, it won’t be difficult for me to deal with them. My English level is intermediate (B1–B2), which allows me to understand the required documentation in a short time. Write me back and let’s start!
