"Louis is definitely 5-star!!! I started working with him in the fall of 2017 on two mobile apps, and will certainly continue using him as my core programmer going forward. Louis is an exceptional programmer, producing elegant code that even I can follow. He is exceptionally fare in billing, quickly grasps what you're trying to do, and is very honest and friendly. Furthermore he does not hesitate to identify issues, solutions, and opportunities to make my apps better, open to upgrading and future enhancement. I would not hesitate for second to recommend him!!!!"
