We found Konstantin after one big and pretty famous web development agency in St. Petersburg failed to do the job for our medical radiologists community, radiomed.ru. The company just took the money and didn’t do anything after six month of so called "development". I admit that the job was not simple (yet really hard) and consisted of several parts, including migration of huge Drupal 6 website with more than 20K nodes and more than 200K comments to the new D7 system, development of several new modules with unique functionality and many more.
When I wrote to Konstantin, he became very interested in our project, and we spent some time discussing the details of the new website. I have to mention that it was a great pleasure to work with Konstantin starting from the very first email and till the day when the work was done. Based on our vision of the new website, he wrote comprehensive plan of site migration, new modules and theme development so we all knew what to expect. My stupid questions were patiently answered, too.
All these things wouldn’t mean anything without Konstantin’s passionate willingness to make the best of what’s possible in every single task. And it’s all combined with his honesty and tendency to make more than was planned for the less money. Yet, there was a bunch of great improvements in our project that were made by Konstantin on his own, and he didn’t charge us any extra for these goodies!
Last, but not least. Konstantin is a great person to talk not only on IT topic. I remember the cute story he told about injured in a car accident dog that he and his wife saved from a certain death. This story is a good illustration to Konstantin’s kind soul, which is when combined with outstanding technological skills makes him the best freelance web developer I ever knew.
Thank you for your great job, Konstantin!
