    Big Data Software Engineer

    Poland - Last active: 5 days ago - Tests: 4

    ======= Over 2000 hours spent on Big Data projects on Odesk! ======= Over the last 5 years, I have worked in different projects, many requiring not only software craftsmanship (OOP design, agile development, TDD) but also a mindset typically needed in research. I love solving problems that require POC type of work and experimenting. I am an advocate of open source solutions, and prefer to work in places that have a startup culture. My competencies lie mainly in software development (Java, Python). Areas of interest: - Big Data and NoSQL technologies (Hadoop, Hive, PIG, Storm, Cassandra, MongoDB, HBase, others), - search (Solr, ElasticSearch) - AI (soft and hard computing techniques), - dynamic programming languages I am always looking for opportunities to expand my toolkit and take part in projects that present a challenge.
