I can provide the referral links and portfolio and you can even verify the projects/products owner about the contribution I had provided to them, I have a variety of best projects completed in the past.
I believe that having an engineering background (and the coding chops to back it up) gives me the strong analytical background necessary to help take product and growth to the next level. Programming languages and frameworks are tools to accomplish a goal. I will work with you to determine the best tool for your goals. Ruby on Rails, React, and Angular have been good choices for recent projects.
Looking forward to politely hearing from you.
