Alex W

I love breaking apart problems and forming a well-thought-out process in solving them. This has influenced my need to lead my clients through requirements analysis, system design and architecture before the start of any project. More often than never, this leads me into not only understanding the problem better understanding the client's business, products, and customers Besides my knack for breaking apart problems, I love working with Python, Java, JavaScript, C++, and many frameworks and too.
