Amazing! Not only was the work completed ahead of schedule, Ken did EXACTLY what I requested. There was no need for a back and fourth conversation. 5 stars for work, price, and timeliness. Thank you Ken!

Portraits of Saints

I had Ken do some work for me on my Shopify store and I am so pleased! He did it so quickly and exactly to my specifications and at a very reasonable fee. It looks better than I imagined. I plan on using his services again and highly recommend him.


I was amazed at how quickly Ken did this work, superfast response to all queries. Was really pleased with the job, functionality exactly as I requested and no problem for Ken to make all the tweaks I needed to get it exactly right. I recommend Ken's work, and will be using him next time I need to make changes to my store.


Amazingly prompt. Excellent communication. Clear commitment to nailing the scenario. Highly recommended.

PS Ken even worked on our project over a holiday! Talk about going above and beyond. Thanks Ken!

Awesome work.

Boardwalk Cafe and Diner

Ken thanks for your patience with getting my site amended. I was very happy with the final functionality. You will be my "go to"person in the future for my Shopify coding needs. Thanks again!

Tiger Tail USA

Ken has been a pleasure to work with and is fast and accurate.


We needed to make some small changes on our website and reached out to Ken for help. Ken was very responsive and prompt with following up. It is not easy to find a developer with excellent communication that also work so efficiently.

Kringles Bakery

Ken was so patient with us. We had our confirmation for orders needing some work to reflect our Bakery's name as well as how it was to be picked up. It did take longer that I thought but I was so busy and didn't respond quickly to Ken's questions. The work was completed and the bill was reasonable which is so important for our small family owned and operated business.
I will definitely choose Ken for any future work with our Shopify account!

Ken is outstanding, courteous and knowledgeable!

Fast response and great price.

Bambu Earth

Ken was quick to respond to my request (and actually has already completed the work and I've yet to hear back from the other 5 people I reached out to). He did the work quickly, efficiently and correctly in the same day I requested. He even worked until after midnight to complete and had it done within an hour or two of starting. I spent a few hours trying to figure it out and finally gave up and he was able to complete it for me in a snap. We were really in crunch time because we launched Bambu Earth on Kickstarter and needed a landing page so I'm extremely pleased with Ken and his quick response. So happy. http://bit.ly/bekickstarter
