 I take my engineering responsibilities very seriously to ensure a safe, efficient and cost effective operation whether in the oilfield or manufacturing environments.  I have strong problem solving skills, collaborate and contribute well in teams, while also functioning effectively with individual responsibilities. I have experience in fast paced and high stress environments, with several ongoing projects and multiple deadlines.  I will no doubt be an asset to your company with my education, strong work ethic, positive attitude and interpersonal skills. I also want a career, not just a position to go by.
