**** ***** *** ******, **********, NC 28401 607-***-****; email: ac2fz7@r.postjobfree.com Mechanical Engineer Technical Lead Analyst Project Manager Consultant Currently exploring opportunities that include: research, development, new products, new processes, new methods, or new technology to solve complex technical problems SUMMARY

I am an experienced engineer who has worked on every stage of product and process development, in a diversity of realms (communications, nuclear, environmental, renewable energy, instrumentation). I have been engaged in solving difficult and varied technical problems, and I have done it successfully. In several cases, my efforts led me to the creation of new methods and new technologies that set us free from the no-solution paradigm and allowed workable solutions (several unique measurement devices, 10 patents and 2 Patent Applications speak to that). I am a very fast learner, data driven decision maker; my broad background often permits me see situations from different (and outside the box) perspectives, allowing me to contribute answers and novel (often simpler) solutions. I have been well trained and experienced in design, not just machine and mechanical design, but system and process design as well. I have worked in direct support of commercial organizations, and sometimes direct support to the costumer. I understand deliverables, deadlines, and budgets. I have troubleshot complex manufacturing, product, and production issues using first principles, modeling, and statistical tools. I am a US Citizen and a registered professional engineer (PE).
