Big Data Machine Learning Engineer with strong computer science, theoretical physics and mathematical background. I've deep understanding of implementing data mining algorithms in a scalable ways, not just using them as consumers. I'm a big fan of Scala, and have been using it to develop scalable and distributed data mining algorithms with Apache Spark. I've involved with open source Apache Spark development as a contributor. Apache Spark is a fast and general engine for large-scale data processing, and it fits into the Hadoop open-source ecosystem. Specialties: 鈥� Machine Learning and Data Mining. 鈥� Distributed/Parallel Computing and Big Data Processing. 鈥� Expert in Apache Hadoop
