I know Mark Patena pretty well, as Mark has helped me several times with website issues in the past few years. Each time, he has been reliable, efficient, and clear. He quickly identifies the root cause, explains what’s happening in a way that’s easy to understand, and fixes problems. We also communicated back and forth whenever I had some questions. He’s responsive, professional, and calm under pressure, which makes a real difference when something on the site is not working as it should. I would happily recommend Mark to anyone who needs general practical IT support for website troubleshooting and fixes.

We highly recommend Mark to set up or fine tune any shopify needs for you or your company. Very pleasant to work with because he listens, executes and delivers on time.
