Polyglot Software Engineer

Profile

If you are searching for a Software Engineer that is passionate about technology and is a proven problem solver, then look no further. I have been teaching myself programming technologies since I was 12 years old. I started with C++, and I am now proficient in over a dozen languages and numerous web and automation technologies.

I consider myself to be a Polyglot Programmer, but my go to languages are Java, Python, Bash and JavaScript. I have a deep understanding of programming fundamentals for the entire product life cycle. From design to deployment, no matter what the language requirements, I would be an asset to your organization.
