Pawel is a software engineer, and is passionate about knowledge sharing. He's especially focused on processing and exploring data sets (be it big or small). Pawel is actively looking around and searching for emerging technologies and tools that will make data science simpler in the future. Loving the idea of the free and open source software, he tries to commit to his personal and external projects from time to time. Pawel is currently at Feedzai where he develops applications that help fight financial transaction fraud, and sees his favorite tools like Pandas, Apache Lucene, ElasticSearch or Akka (just to name a few), being applied to real world problems. He develops in Scala, Python and Java, but no language is a bad language for him.
