"Hello Alex, Wanted to thank you for an excellent class at Penn State and look forward to further classes in the future. … you are one of the best instructors I ever meet [sic] when it comes to the Plone CMS."
"Alex brought deep experience and unmatched professionalism to his engagement with National Geographic. His work facilitating communication and promoting best practices across a geographically dispersed development team was crucial to the success of our project."
"In 2006, Alex helped Radio Free Asia move their website content from Bricolage to Plone. This was a challenging task not many were willing to undertake, so we especially appreciate his skill and dedication to our project."
"Alex was able to revive a very important part of our web site - a Python job I'm not sure anyone else would have had the expertise or patience to complete. My experiences with ACLARK.NET have always been exceptional, and I would happily engage Alex for future projects."
"It is a relief to know ACLARK.NET is there to back up our corporate systems; consistent high-quality service and a trustworthy company."
"Alex is a brilliant engineer and terrific at completing his commitments! If you use Alex, you won't be sorry!!"
"We're really happy with what you've made for us. I know you really worked long and hard, and even longer and harder, on the project, and we are most satisfied and appreciative. And just plain pleased — it has been great to work with you."
"Thank you (among other things) for 'Plone 3.3 site administration'. Hopefully you'll publish 'Plone 4 administration' some day ..."
"Even though he primarily specializes in Python Web Development, Alex was tremendously helpful with our Joomla! website; he performed PHP upgrades, security updates and other miscellaneous tasks; we were very happy with his work."
"I got what I expected from our initial conversations and I'm pleased with the result. Thanks for the nice work. It looks really good."
"Alex and his company successfully bid to perform enhancements to the Land Trust Alliance website in July 2011 and have been doing routine development and maintenance ever since. We are very happy with their performance, and the performance of our site!"
"Thanks for all your support and help on our website, excited to see it live!"
"Alex became our 'Plone calendar wizard' in 2007 and has been keeping our website running smoothly ever since."
