Client Case Studies

In 2010 I started Tech Savvy NYC offering “big agency services for small businesses”.

As proof of talents, skills and past success I offer many referrals and recommendations, as well as live website examples, and quantifiable case studies. I am extremely competitive in my own business and for my clients.

A significant indicator of what we can do is what the team has done already and accomplished so far. Here you will find live examples of the websites we have built and businesses that we have helped grow.


Client Websites and Case Studies

One of the most perplexing things to me about competitor websites is they rarely provide actual links to live examples of the websites they have built or businesses they have helped grow. This is true of the biggest and costliest agencies locally.
