Nicholas in a few words

I have been coding professionally for 15 years. I worked 9 years in the silicon valley including a year and a half with Apple.
Apart from Apple I have mostly worked with startups. I have had a lasting drastic impact on every engineering team I've come across. I was the first engineer hired at Pricematch a company that has since sold to

Nicholas is very detail oriented and produced great results for the company. He is a very talented engineer and I highly recommend him.

I worked with Nick on a very complex web application. Most of what we created was never done in a web app before so there was a huge learning curve. Nick was always eager to learn new concepts and work hard to create an amazing application.
