I was always impressed by the breadth and depth of his knowledge, and how effectively he shared it with the team. Marek is a true Python expert. He knows the language, tools, libraries, frameworks, design patters, in and out. The whole team benefited greatly from his knowledge, during design sessions and code reviews. We got get better code, faster. This was not limited to Python code. Marek has a great design sense. He came up with some of the best designs I've seen, combining simplicity with flexibility and extensibility. He is fluent in multiple programming languages from multiple paradigms -- I suspect that drawing from this broad experience is what lets him create those elegant designs. Marek is passionate about code quality in a truly agile sense. His changes would always make the code better -- easier to read, maintain and change. He saw the need for, and implemented a unit-testing framework for our key component. It was joy to work with, and made the team much more productive. We were able to change this component faster by easily testing our code on local box, and we avoided a lot of regression bugs. A DB-schema management library he implemented was also a great help in making our team's system more predictable, and easier to test and upgrade. He introduced several other similar improvements, making our code better, infrastructure more robust, and team more agile. I'm very happy to recommend Marek and can only hope our paths cross again!", "I had the luck of working with Marek at Amazon in the AWS Elastic Block Store team. I was his peer for a brief period and then his manager. Marek is an outstanding developer, smart and extremely productive, with excellent knowledge regarding a broad range of technologies. He has made a positive impact on our team right away, by the end of his first sprint (3 weeks) he was performing challenging deployments, operational tasks, and performance fixes. Three months later he was a fully fledged team member owning large features, and making a significant contribution to our designs. His work is of great quality, and every component that he has changed he has left in a better shape. Almost always this has meant that the component had improved test coverage, and that the code has been refactored for the better. He is very productive, and the code that he produces is of high quality - at times it was hard to keep up with the code reviews given how much code he could write. He is energetic, passionate and openly self critical. I recommend Marek without reservations, he's an asset to any team, I would love to work with him again.", and "Marek is a brilliant programmer, great team player and excellent analytic."
