About Ryan Holzer

Ryan Holzer is a Staff Software Engineer at Corteva at Corteva Agriscience. He possess expertise in web development, css, actionscript, digital marketing, javascript and 31 more skills. Colleagues describe him as "It is rare that you come across a supervisor like Ryan. I have yet to work under the wing of a person who is more a mentor than a supervisor. Working with Ryan has been pure pleasure – I have learned all that I know about development from him and he has been kind and patient with me all the time during my internship at Two Rivers Marketing. Being one of the greatest mentors I have met, he is always the “go to person” when I encounter any problems during my time at Two Rivers Marketing. He always looks out for his team whenever we need him. I recommend Ryan highly as I know that he will never let anyone down. Any employee would be lucky to have Ryan as a supervisor/manager." and "It is an honor to recommend Ryan who is one of the best team players I have encountered in my career. From day one, I found that Ryan is definitely the “go-to” guy for seemingly unworkable situations! His methods of observation throughout the entire design process allow him to quickly and very successfully find a solution. Most appreciated is Ryan’s ability to grasp difficult concepts and educate himself thoroughly when faced with the most challenging design dilemma, especially with time-sensitive material. He is never hesitant to reach beyond his comfort zone. If Ryan cannot immediately find a solution, he is quick to research and find the best resolution. Not only does he contribute immensely to each project, he is also willing to help his teammates by teaching them in such a manner that builds confidence – never allowing someone to feel he or she has been degraded. Ryan is far and beyond an amazing asset to any project!"

Listed skills include Web Development, Css, Actionscript, Digital Marketing, and 32 others.
