Denes is highly skilled and very very knowledgeable at what he does, especially with joomla, which is knows inside out. I would put his level of expertise at the PRO level. Joomla is like a walk in the park for Denes and it shows in how fast he resolves and finishes set tasks. A friendly guy who goes that extra step to help his clients.
Successful websites evolve. Even when that spiffy new site is up and drawing traffic, the job is not complete. There’s always website maintenance service work to be done for SEO, performance and security.
