Groovy & Grails, Java - Freelance Developer

Australia - Tests: 2 - Portfolio: 2

On the author list of bitcoinj project . However I did only contribute one patch, nonetheless this required reading c code and translating functionality into java. Worked with linux for 4 years, primarily Ubuntu. Eclipse is my primary Integrated Development Environment(IDE). Initially began programming with python, learnt a little bit of C++, including integration of python and C++. Unfortunately it has been at least 2 years since working with python and C++, so my knowledge of libraries and the languages has diminished. Currently spending a lot of time with Groovy and GRails. In the last two years programmed primarily in Java. Have experimented with github. Proficient in HTML5, CSS3, and javascript. Can read and write UML diagrams.

Groovy On Grails Developer

India - 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 made 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. 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 grails for providing data 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 ;)

Ruslan B.

Server-side (backend) developer: Java, Groovy, Grails, Spring

Russia - Tests: 2 - Portfolio: 4

I have 15 years of experience in software development, 10 years of Java experience. I worked in many areas, for both local and international companies. I have got a full-time job, but I'm interested in getting a few more freedom for myself while getting new exciting tasks to do. My primary programming platform is Java+Groovy (and Grails). I am experienced with Grails guts as well (Spring, Hibernate). I am familiar with Quartz and Atmosphere. I also worked with some assembly language, basic (and vb), pascal (and delphi), C++, C#, ActionScript 3, Objective C, Perl and PHP. I have some basic knowledge of lua, tcl, python (I can modify/fix existing code). But these are secondary tools, my primary language and area of interest are Java and Groovy. I know the NoSQL and map-reduce principles, and worked with MongoDB and Cassandra as well as traditional relational databases (MySQL, PostgreSQL, Firebird). I was working in a teams (though maximum was 5 developers only) so I'm familiar with the bug-trackers, version control systems (svn, git, perforce, and even cvs), I love maven and gradle, also love the continous integration tools like Jenkins and Teamcity. As you might guess, I am a fast learner. I like to do complicated tasks. Unlike many other developers, I like to deal with code written by others. I like to debug and profile it, to refactor etc. I'm not fanatic of code improvement (if it works it's good enough), but when I see the portion of code which is hard to understand or which can cause bottlenecks or which is dangerous - I'll fix it :). Together with software development, I like some minor reverse-engineering. I was used to do some work with IDA, and ofcourse with JAD (and now with JD). I used some ActionScript decompiling tools when dealing with AS3 project. Also I know about web application protection. I always escape user input, filtering unnecessary stuff when needed. I won't do chmod 777 anything at your server as well. I'm a very cross-platform guy. I use linux, mac os and windows and I know how to launch your java app on these platforms natively. I don't hesitate to ask the questions when I'm unsure about the task. I believe it's better to seem stupid than waste my time and produce the bad implementation. I always do my best to meet the deadline. I'm not looking for a single job for a few hours only (although I like this kind of jobs), I'm looking forward to "win - win" relation, where you can be sure I meet your conditions and I can be sure you'll provide me with some interesting tasks, promt payments and clear directions. You're more than welcome to contact me and ask any questions about my background or experience. I'm available for voice communication too, evening time only (starting from 15:00 GMT or 7am PST). If we work long-term you'll have more contact options. I'm available on Skype, Jabber, Viber. Last but not least: I've got 2 broadband connections at home, and I'm always online on my phone, so I won't get lost.
