SUMMARY

Seasoned software engineering generalist with over a decade of programming experience. I've worked in companies ranging from start-ups to Fortune 500, writing consumer software products, web applications, and internal-use systems applications, using a myriad of technologies, primarily Perl and SQL, but also Python, Java, C, HTML, XHTML, XML, CSS, and Javascript for primarily Unix and Linux environments such as FreeBSD and Ubuntu. I also hold a bachelor's degree in Business Administration which gives me a broader sense of business functions and operations.
