    Emil Drkušić

    experienced database developer, programmer, financial analyst

    Croatia - Last active: 11 hours ago - Tests: 1

    My jobs so far included analysis of customer requirements, consulting, coding and deployment on two major projects (one was developing ERP for telecommunication sales company and other was on-line system for tracking shares and funds values), work on few smaller projects and teaching (databases, math, programming, logic). Most of smaller projects were applications based on MS Access, usually connected to MS Excel as data source or output for further analysis. Most of my work was/is related with databases from database modeling and coding and than producing complete applications with GUI. Technologies I used so far were MS-SQL, MySQL, MS Access+Ms Excel (few complete applications with more than 50 forms each in usage by clients), C++, Pascal. Maybe most interesting is development of complete MS Access applications as well as using VBA in Access or/and Excel, but feel free to contact me for any of above. I think that my experience and knowledge are enough to get job done faster (and of course cheaper) but not loosing any quality in process.

    Java,Grails,Google Script & Twitter Api Expert

    India - Last active: 3 days ago - Tests: 10 - Portfolio: 5

    Besides being an excellent communicator, I am a freelancer consultant with expertise over web,desktop and mobile applications. Till date I have obtained over 50 5* reviews which are true testimonials to the quality of service I have delivered. I am an express learner and I adapt and become adept to new technologies very fast. This is clearly reflected by my job history which shows the wildly different variety of jobs I have worked with and landed them to perfection. I have experience and mastery over several regimes. Primarily I am a java buff as I work with Groovy/Grails for web development and Android for mobile development. Both require supreme expertise over java. I have mad a lot of applications using twtiter api. If its about twitter, its about me! Just see the jobs I have done for twitter in my job history and you will realize why I claim that. I am also proficient in making bots,web crawlers, email scrapers , automation tasks based on selenium web driver/htmlunit and jsoup. I have been heralded as the "bot master" by various clients I have worked with due to my outstanding performance in automation jobs. The reason for my success over each job I work upon is my exposure to a plethora of technologies which adds an extra edge to my artillery. I have worked on wildly diverse technologies including: 1) Web Application development: For web application development, I have experience with Grails- Groovy on Rails. I am a master of this wonderful framework developed to make java development really easy and rapid. My role in past projects on grails includes implementation of Restful web services for sql/nosql databases as well as overall application design/development right from the inception to transition/deployment. 2) DBMS: I have worked on sql as well as no-sql. In sql, I have experience with MySql,Sql Server(2008),DB2,Oracle RDBMS. In no-sql, I am a mongoDB master. I have also worked with CouchDB(with android). 3) Desktop Applications: I have made several desktop applications using java swing and javafx. I also have knowledge of Griffon (Grails for desktop). All my applications are characterized by thread safety and robust framework architecture. 4) Mobile Application Development: I have good experience with android framework. All the apps I have worked with are characterized by nice UI and a stable lifecycle by proper handling of application states. My strength over core java concepts like multithreading, runtime polymorphism, inheritance comes in very handy with android app development. Apart from these, I can make background web services using ruby on rails/grails for providing RESTful web services to mobile applications. So you can find a full stack developer in me. 5) Scripting: I have developed various scripts using google app scripts, python and ruby. I have a full fledged ERP running on google drive using google app script with 0 cost for hosting. I always use the best technology for my clients which is light upon their budget. But above all, I consider strong communication skills as my killer strength due to which I got so much success in such a short span of time over this platform. Indeed you would love interacting with me- ITS A GUARANTEE ;)
