A little bit about me: I'm generally a very calm and stress-resilient person. I'm quite persistent - that is, I won't go to bed until the job is done - and I always pay attention to the details. I'm eager to learn, and I'm usually able to find out the necessary information by myself. I'm patient, I have good critical thinking skills, and I'm told I also have a good sense of humor :) My programming skills: Fullstack Development: - JavaScript + TypeScript - Node.js, Express.js, Koa - MongoDB - REST API - Jest - HTML, CSS, JQuery, JSON Python: data scraping, data structuring and analysis, back-end developing, chatbots - Beautiful Soup - Pandas - Selenium - NumPy I also have a lot of experience with Power Query M - language used in Microsoft Excel and Power BI.
