Carlos C.

I work hand in hand with you to simplify and sharpen your project, then build it right the first time. Top Rated on Upwork, over $60K earned, every project rated 5 stars. 15+ years and 800+ projects across web, mobile, AI and interactive installations, including work for LG, Reebok and Cisco. Computer Science, University of Central Florida. I run two technology companies, Touch Data and Synapsa, so I scope and quote work, not just build it, and I think about what something costs to run long term, not only what it costs to build. US hours from Peru (UTC-5, same as Eastern), fluent English, and everything set up in your own accounts so nothing depends on me afterward. Happy to advise on the right approach before any work starts, at no cost to you.
