What my clients say about my work

I’ve been fortunate to work with many wonderful clients over the past 30 years

“Whether it be our winery operation or my previous consulting business, Karim by far delivered the most value for the dollars spent. That includes looking at competitive bids from other firms who specialized in our industry. From design to delivery to performance, hands down the best value.”

Paul Pease

“Our company has worked with Karim for over 15 years. He developed our website and is ALWAYS very responsive and professional when we need changes. Most importantly, he is an expert on the latest web technology and often has a better way to do something. This happened most recently when Karim suggested a different technique to achieve my objective. He is a MOST VALUED member of our technical team. I highly recommend Karim.”

Recovery Press LLC

“We were looking for someone to help us migrate our website from Wix to Square's Online store. Karim Ardalan was recommended to us and when we contacted him, he understood the issues and elements that we were trying to incorporate in the new site. Karim listened very carefully and designed a perfect plan to tackle all the issues. He delivered on time and flawlessly. His quote for the project was one of the most reasonable ones that we had received. Even though we added more elements to the project, they kept the original quote for the final invoice. All in all, I would give them 6 stars, if I could!”

“Karim was very clear and understandable. Has very special teaching approach. Felt very comfortable and eager to learn. I will be doing business with him without question.”

“I wasted hours trying to get answers from searching, forums, chats ... and everything but crystal balls and Ouija boards. Karim answered my questions, emailed me links and gave me encouragement in ten minutes! I will hire when needed!”
