    I'm a software developer from India with a breadth of development experience including desktop and web applications using Java, build engineering, and web application development using python/Django. I also have experience in working on components like ADF which is a JSF implementation. Also on wide variety of web servers likes of Tomcat , Apache , Weblogic Server . Unlike many programmers I have a thorough knowledge of my craft and rather than hammer away on projects I use my solid problem solving skills to think through the problem at hand and devise an intelligent solution. I believe in approaching work with a view of scalable long term solutions rather than short term hacks , while honoring the time line. In addition to knowledge in a breadth of programming languages (Java, Python) that I can use to create custom business software solutions, I also am well versed in the administration and maintenance of common web application environments. Programming skills apart, I have a good command of the English language to be able to articulate thoughts very well and that makes me a great Content writer. My ability and skills in researching for information are honed over 10 years of working with many big guns in the Software industry. I can deliver content and articles that perfectly match your requirement, are concise and effective. If you're looking for a moderately priced alternative to American programmers who has the same skill set, ability to communicate effectively in English, and a history of delivering completed work on time and as directed I'm your guy.  less

    My name is Aleks and I am located in Lisbon, Portugal (originally I am from Germany). I've been a software developer for 20 years and have worked for startups (+2 years), in publishing (+1 year), automotive (+6 years), telecommunications (+2 years) and as a freelancer (+7 years). My goto language for backend systems is usually Java, but on occasions I've used C#, C/C++, J2ME and Scala, Node.js, PHP and Perl... and a lot of Bash scripts. I use the Spring framework as a foundation for most of my projects, and when ever possible in combination with Spring Boot. In recent years (+4) I've been doing a lot of HTML(5) based frontend development for various projects (mostly with AngularJS and Bootstrap), but have done UI development also with Spring MVC, Thymleaf, Freemarker, Velocity, JSF, ASP.NET, the Eclipse Platform and have developed Flash/AS3 apps extensively. Besides developing software, I am also assisting clients with their server infrastructure. My preferred software stack is Ubuntu Linux, Docker, Apache HTTPD, Nginx, HA Proxy. My development environment is Linux based and therefor I try very hard (and usually succeed) that my products run on any operating system. Build tools (Maven, Gradle, Grunt.js, Gulp.js, Make), version control (Git/Git Flow), continuous integration/build (Jenkins) and issue trackers (Trello, Github, Bitbucket) are essential for my work organization. Portfolio available on request in private Bitbucket repositories. The things I am tinkering with in my spare time are available on Github (https://github.com/vidakovic and https://github.com/monkeysintown).  less
