    During the past 17 years, I've developed both Internet sites and Intranet/enterprise systems - from news portals to dating sites to ISP billing systems to HVAC controllers to Logistics Management systems, and more. My core skills are Java/J2EE, with experience in both commercial (Orion, WebSphere) and open-source (JBoss, Tomcat, Glassfish) application servers and most popular databases (MySQL, Oracle, MS SQL Server, Sybase, etc). I have a good understanding of modern Web technologies and several years of experience developing Web applications using Vaadin Framework, but my primary focus and my primary strength are backend technology stacks. I have experience with developing highly scalable clustered systems supporting up to 8000 concurrent online users. I'm familiar with in-memory data grids (like Hazelcast), NoSQL databases (like AWS DynamoDB and MongoDB) and other high-load/high-availability technologies. I have extensive experience developing applications that run on Amazon Web Services cloud computing platform. I'm familiar with all phases of software development - from coming up with functional requirements to design, development and testing/support. I've been leading teams of up to 10 developers, as well as managing projects lasting up to 5 years. I have good working knowledge of Scrum agile software development methodology. I'm a long-time open-source proponent. Over the years, I've contributed to several open-source research projects, such as Freenet and I2P. I develop some of my own open-source projects as a hobby in my spare time. I hold a position of research fellow at the Department of Computer Science, Lomonosov Moscow State University (my primary scientific interests are small-world peer-to-peer networks, natural language processing and application configuration management), and for this reason I, unfortunately, can't accept jobs that absolutely require more than 30 work hours per week. **I'm looking for opportunities to work on your Web or internal project using Java/J2EE technology stack, as well as to manage a software/Web development project.**

    I have extensive experience in data scraping and data manipulation. I am new freelancer here, but you won't regret it if you give me a chance. While working in this area (almost 6 years) I have scraped more than 1000 different kinds of websites (search engines, e-commerce, protected websites, protected with cloudflare, with login, with limited number of requests using proxies...) and worked with different kinds of databases (Amazon DynamoDb, Amazon Redshift, MongoDb, MySql, Postgres...). I have graduated on Faculty of Science and Mathematics (average grade 8.88). Successfully participated in big scraping projects but I am willing to learn more and improve in this area. - Have an experience working with SQL, PostgreSQL, XML, JSON... - Have an experience with linux server and remote access (ssh, ftp). - The area I am most interested in is web scraping and data extraction using Python/BeautifullSoup/Sellenium/Scrapy/Regex... - Another area where I am improving my skills is data analytics (Pandas, Numpy, Tableau...) I think I am communicative, open to cooperation, independent and a team player.
