  5. Matthew Fowler

    Matthew Fowler

    Software Engineer Specializing in Java, iOS and We App Development

    United States - Tests: 2 - Portfolio: 1

    As a software engineer, your greatest asset is time. Developers are expensive. Developers who write unmaintainable code are unimaginably more so expensive, leaving behind a mess that can introduce bugs, delay features, or at worst, kill a software project in its tracks. I have cultivated a passion for clean, maintainable code that is easily modifiable and understandable by any developer. Using techniques such as test driven development and refactoring whenever needed, I feel like one can create an environment where features can be delivered at a sustainable pace with minimal risk. All this while keeping the confidence that these features and all past features are kept in a working state. My primary interests as a developer are agile practices, TDD, XP, mobile software engineering (iOS), client/server web app development, big data, functional programming and algorithmically challenging problems.
