    Senior .NET Developer

    Romania - Tests: 6 - Portfolio: 4

    I am a senior .NET programmer with over 20 years of professional experience, mainly in back-end C# applications using SQL databases - web services and Windows services. I am very familiar with SQL data modeling and normalization up to third normal form. One of my recent accomplishments was changing an error-prone, manual process that was taking three days each month into an automated, five-minute scheduled task using MS SQL Data Tools. Unit testing and test-driven design are very important to me - I wrote a book, TDD by Example, available on Amazon. I don't mind working on pre-existing code without tests but I generally insist on adding them to any code I change.

    Maciej Zubala Agency Contractor

    Senior Ruby On Rails developer

    Poland - Tests: 4 - Portfolio: 6

    Software development is not only my profession but also my greatest passion and hobby. This is why I spend majority of my free time improving my programming skills, learning new concepts, technologies, languages and tools. I get the greatest satisfaction when products I develop are released to the world and people start using it - that makes me want to spend more time at work. When not in front of my monitor, I'm probably taking care of my daughter or doing some sports (tennis and swimming most of the time).
