I've fine-tuned my skills with Apache Spark, Apache Flink, Hadoop, and a range of associated technologies such as HBase, Cassandra, MongoDB, Ignite, MapReduce, Apache Pig, Apache Crunch and RHadoop. Initially, I worked extensively with on-premise environments but over the past five years my focus has shifted predominantly to cloud based platforms. I've dedicated over two years to mastering Azure and I’m currently immersed in AWS. I have a great experience with Linux environments as well as strong knowledge in programming languages like Scala (8+ years) and Java (15+ years). In my earlier career phases, I had experience working with Java web applications and Java EE applications, primarily leveraging the WebLogic application server and databases like SQL Server, MySQL, and Oracle.

Over 7 years of extensive experience of working with Oracle (working with stored objects, writing sql query and pl/sql), various Java application servers (JBoss, Weblogic, WebSphere) and Java Framework (Spring, Hibernate) for the largest service and telecom providers in the world (Telecom New Zealand, Deutsche Telekom, VimpelCom and so on) and online advertising companies ( Forbes, Leboncoin, Bauer and so on)

I'm a highly experienced software engineer with great, proven feedback and more than 10,000 hours tracked here at Upwork. Specialization: ★ Web-development ★ Scrapers ★ Big data and data processing Before I decided to work as a freelancer, I used to be a programmer and CTO, so I have deep knowledge of both business needs and appropriate technical solutions. I also have a great understanding of low-level computer principles and codes; I have been writing some C++ and x86 assembler codes for a few years. I've been coding since I was 14. As a student, I took part in an IT competition and won 3rd place in my city. Most of these competitions strongly relies on algorithms and mathematics, so I do have knowledge of programming patterns and algorithms as well. I switched to Python as my main programming language more than 7 years ago. I found it simple, clean, reliable and powerful. Soon after that, I noticed Django and started using it when it was an early pre-release version. Whether you need a complex, corporate-level solution such as a social network, or just a small script performing a simple task - I will do it quick and efficient. How a good IT solution should look like? It must be: - reliable: I always test my code; - solid: I think through all the important details and features before typing any symbol of code; - complete: my solutions will satisfy your business needs for 100% and even more; - high-quality: forget about stupid or unclear code - I follow all the theoretical and practical principles of writing code (including standards such as PEP8). The list of technologies and programs I worked with: ★ Python, Django, Flask, many external Python libraries ★ CSS, HTML, Java Script (including libraries such as jQuery) ★ MySQL, PostgreSQL, Cassandra, MongoDB, SQLite ★ Lighttpd, Nginx, Apache, Cherokee, Tornado ★ Hadoop, Spark, MRJob ★ High-load optimization (including creating the appropriate project architecture, database design, code refactoring, choosing right tools etc.) ★ Selenium ★ Git, Mercurial; Github.com, Bitbucket.com, Basecamp.com ★ Many data formats and files, such as binary, graphic, audio, plain-text, CSV, XML, OpenOffice and MS Word formats ★ Mac OS, Linux (including console and server administration), Windows, iOS, Android ★ PyCharm, Sublime Text, Text Mate, nano, vim; intermediate Photoshop skills
