Daniel is an amazing developer and so much fun to work with. Daniel was part of our little team at MECLABS and helped us to create processes and procedures within the Technology group as well as teach all of us so much! Anytime I had a question or problem, Daniel was my go to person to help come up with a solution that would work not only for today, but also for the long term without taking months to implement. He was always willing to put in the time and effort needed to make every project succeed and did everything with a smile on his face. Daniel kept us all laughing while ensure the team grew and produced the best possible software.

Daniel was the cornerstone of our application development efforts. He is extremely knowledgeable in many areas of web development, including PHP, AJAX, MySQL, and Flash/Flex. Perhaps an even greater asset to us was his overall skill with Linux, Apache, and many aspects of web/application/database server administration. Aside from his technical expertise, he was also a very strong member of the team. He was always friendly and consultative with both internal and external customers. He is extremely adept at finding effective solutions to complex problems.

I worked very closely with Daniel as part of a small development team and he consistently proved to be an extremely knowledgeable and capable developer. Daniel also displayed his flexibility and intelligence by performing application development as well as server administration. I would recommend Daniel to anyone needing a competent developer or skilled server administrator.

Not just a great developer, but a well of good ideas, out-of-the-box thinker, and great communicator… I have worked in Web development/marketing for over 7 years now, and in that time have worked with many developers. By a long shot, I enjoyed working with Daniel the most. Let’s be honest developers can be had on the cheap, and from many sources. What Daniel gave me was quality work, drive to solve problems (not just make it good enough), give feedback on different ways to accomplish the desired goal with considering secondary items like SEO and Usability, and can express problems in a very understandable way. The abilities that Daniel offered in concert together, is something I have not found here in the states, or even abroud. Communication was also an essential working quality that I needed from Daniel, as I was a bridge from development to client. He continually helped communicate to me and client’s complex items that we happening or fixes to be developed. He would take the time to help you understand even complex situations going on. I cannot speak enough good things about working with Daniel, and it was tough to see him move on. Whenever I do outside contract work, Daniel will be the first one I will call.

Daniel was a great asset to the company. He is very knowledgeable and an excellent programmer. It was a privilege to work with him.

I worked with Daniel across a wide spectrum of projects ranging from cutting-edge social media API integration, requiring up-to-the-minute knowledge of changing APIs, to extensive database development focused on delivering a range of information in a variety of cross cuts and formats. Complex cart process buildout and advanced metrics tracking were the regular. During this time, I was able to focus on getting clients results, because not once did I have to second guess build quality. Daniel has that ultra rare ability to foresee hidden obstacles, solve them and have the project complete before you even have a chance to ask for an update. The definition of a professional, his work is second to none. I would recommend his work and character without hesitation.
