### Software Development Engineer II @ Amazon
Jan 2013 – Jan 2015 | Seattle, Washington, United States
Responsible for large scale monitoring and data analysis service within Elastic Block Store (EBS), part of Amazon Web Services.

### Senior Software Engineer @ Google
Jan 2012 – Jan 2013
Joined Google when Motorola (which was part of Google at the time) acquired SetJam for the TV and movie data normalization system we've created. I was responsible for adding more features to the existing system as well as preparing it to support multiple clients within the company.

### Senior Software Engineer @ SetJam
Jan 2010 – Jan 2012
Created a unique service to normalize TV and movie data across multiple online sources. Architected major parts of the backend (data processing, storage and output layers) as well as frontend (single-page web application for QA). I've also worked on several classifiers, including hierarchical, Naive Bayes, and Smith-Waterman-based one. Together they allowed us to achieve error rate of less than 2% on very noisy data (errors, duplicates, missing features, different views). 

Got acquired by Motorola Mobility.

### Lead Software Engineer @ Fundacja Nowoczesna Polska / Modern Poland Foundation
Jan 2007 – Jan 2010 | Warsaw Area, Poland
Created webpage and publishing tools for the biggest Polish online library, WolneLektury.pl. My work included designing and implementing a single-page online WYSIWYG book editor, Mercurial-based data storage layer and converters from XML-based data format to HTML, TXT and EPUB.

Code I've written is open-source and available on GitHub (http://github.com/fnp).
