We're looking for an extra team member that likes to join my team! We're a fun team (I hope), you don't need to work fulltime (but you can if you like!), best would be if you speak a little Russian as it can make communication with main developer easy. However your English should be good as well to talk with the rest of the team :) Of course we work with git and simply chat/discuss a lot on Skype. We only work on own projects and don't work for other companies, we develop our own websites/products. Currently we need an extra boost on a few drupal 7 projects, we need you to be creative and proactive to find solutions and even add some extra features you think are missing.... We've multiple projects you can work on, and no real hurry on the projects.. so relax working parttime or fulltime! The time indication is just needed for upwork, but there is enough work for you as long as you like. (Woehoee!)

Hi, I'm in need of connecting with a skilled database developer who is proficient in databasing XML into MS Access and SQL. The XML file is very large and complex. A previous developer did most of the work already. I need to continue with the next phase, but he is so busy with other work, I unfortunately need to find someone else at this point. But I think he did a good job. The new developer would have to read the specs and get to understand what he did to date. Then take it to the next level. The database will be connected to an email application and Salesforce. Preference will be given to applicants who have experience in email server administration as well. I have specs to review if interested. Thanks, Emily
