Orville Weyrich Software Engineer

I am experienced in, and enjoy all aspects of, the software engineering process, from requirements gathering through coding, testing, deployment, and sustaining. I am seeking a position in Phoenix, Scottsdale, Tempe, Mesa, Chandler, or Gilbert Arizona that can utilize my talents and energy. I am also open to relocation for the right opportunity.

I am accustomed to working in a "team lead" model in which I am typically responsible for full life-cycle support from requirements through sustaining, and in which I interact with other domain specialists as peers as needed; I am flexible and adapt to other business models as well.

I am comfortable presenting and documenting computer topics for wide-ranging audiences, and have teaching experience from the community college/trade-school level to the graduate level. I enjoy mentoring my co-workers.

I look forward to discussing how we can apply my skills to meet your software engineering needs. Please see my contact information at the bottom of this web page. Thanks for your interest.
