    I am a senior Software Engineer and a Technical Lead thoroughly experienced in the full software life-cycle. With me on board, you can afford the comfort of focusing on the business aspects while I will care about the technology, and I'll always give you the full control over all business affecting decisions. In terms of new projects, I am offering an end-to-end know-how, from the initial project concept (requirements engineering to accurately capture and analyze your business needs) through software design (elaboration of system architecture, detailed design of components), and software implementation (writing the source code, documentation, and unit testing). I'm specializing in hands-on web technologies, server administration, and security. I have 7 years of experience, working with high-quality CMS/e-commerce systems, web portals, and other solutions. My knowledge includes maintaining mission-critical software in production, designing and developing new software, and always caring about most modern technologies, and best practices to achieve results on time, on budget, within specification. I am highly competitive and very well qualified in practice and research of software engineering. I am a member of two largest occupational societies for software engineers (IEEE, ACM), have a Software Engineering Master's Degree from the University of West London, and 7 years of experience. Software implementation in Java, including web services, Agile, knowledge of many existing CMS/e-commerce systems, payment gateways, CDN, Amazon EC2, JIRA, Confluence, GIT, SVN, Ant, Maven, and many other technologies. In terms of Java, I've been usually developing with Spring MVC, Hibernate, EJB, JMS, JAX-* (REST, SOAP, XML). Knowledge of web containers and application servers including JBoss, Glassfish, Tomcat. Other than that, I am proficient in advanced features of MySQL with InnoDB, PostgreSQL incl. some PL/SQL, jQuery JavaScript library, valid & semantic markup, Twitter Bootstrap. Apart from Web Development, I am also good at developing system utilities in C/C++, BASH scripts, and other solutions. As an administrator, I can design, install, and configure new servers and workstations. I can setup your tomcat, apache, MySQL (incl. replication), mail server, ssh, ftp, shared disks (samba), crontabs, automatic backups, rsync, logging daemons, and more. As a security specialist, I can identify weaknesses and vulnerabilities in the developed software, propose solutions, and suggest or implement preventive measures to avoid the recurrence. I can keep your servers secure to regularly pass the PCI-DSS certification and help you to protect your data by selecting and enabling the most appropriate encryption which goes in hand with designing a reliable data backup plan. My biggest strengths are understanding your business needs, applying analytic skills to propose your technical solution, communication skills incl. presentations and team mentoring, problem-solving skills to break through challenging tasks, and research skills to find the most feasible solutions to brand new problems of today and tomorrow.  less

    I have been developing software collectively for just over 10 years, with the bulk of my experience in the web domain. I have developed numerous public and private sector web applications serving a variety of purposes ranging from eCommerce and content management customizations to problem tracking systems and directory administration tools. I follow agile software development methodologies and have strong communications principles that ensure my customers are receiving timely updates and able to see rapid results on software projects. What sets me apart from other software engineers is I strive to utilize best practices for software development. These best practices include test-driven development, continuous integration, adhering to standards, not re-inventing the wheel, and documenting everything. While this results in spending a little more up-front time developing the software, I believe it is well worth it in order to leave the project in excellent condition so that it can easily be extended and maintained for years to come. My language strengths are PHP, C#, and Java with experience in the Zend and Castle MVC frameworks, PHPUnit, NUnit, and JUnit testing frameworks, and the Dojo JavaScript library. In addition to being an extremely skilled software engineer, I have honed my experience with systems administration as well. I am extremely skilled in administering both Windows and Linux servers, as I have been administering servers and operating systems for a combined 15+ years. I have in-depth experience with all Windows flavors, especially Windows Server 2000-2008, as well as Linux (Gentoo, RedHat, Debian, Ubuntu, SuSE, and CentOS), FreeBSD, Solaris, and VMware ESX 3.5-4.0. For all of these servers, I have experience setting up and designing OpenLDAP or Active Directory installs, file sharing services through Samba, AppleTalk, CIFS, NFS, and FTP(S), e-mail using Postfix and Sendmail, web services through Apache and IIS, and numerous database servers including Microsoft SQL Server, MySQL, and PostgreSQL. Finally, I strive to educate others with the information and experiences I have learned. I do this through community contribution at user groups, tech fests, conferences, and as a member of any team I'm a part of.

    Are you looking for someone with a vast amount of expertise? Look no further. I am also looking for interesting web design and programming jobs. Mostly interested in building something from scratch (or converting / rebuilding existing sites) but if there's a need to fix your project or optimize it you can also count on me. I learn fast and understand concepts clearly. Besides I understand business requirements and can design, plan and make your application work as you wanted. I can also write or record (video) useful documentation / tutorials for you and that are the best for any user. At the same time having a simple, easy to use interface that does not need an explanation is a must in my opinion. I have 7+ years of experience designing and optimizing databases and websites for all kinds of clients, from small businesses to medium-sized international companies. I can also set up and transfer websites on Linux and Windows systems. If you have no experience I can pick a good web hosting company for your site too - based on your requirements. My main area of expertise lies in: - CMS Systems like Drupal and Joomla with an occasional Concrete5 and Silverstripe thrown in. I also count Wordpress here. - Django (the python framework for rapid application development for perfectionists with deadlines) - Ruby on Rails - AJAX / Javascript frameworks to add usability enhancements or just looks (YUI, Jquery, Jquery UI, Prototype, Dojo, etc.) - SEO Optimization (semantic layout, clean urls, keywords) - Some Adobe Flash / Flex RIA knowledge, and integration of Flex with Drupal - Some experience with creating OSX applications (in Cocoa) I can set up a webshop, a blog, a subscription based site, or anything you can come up with. You won't be disappointed. I know that my rate is not the cheapest, but it's still not as high as it might be if you look locally. Furthermore my English is excellent, I am a one-man company right now, thus I am project-manager and developer/designer in one. If this is not what you want, please do not bother trying to hire me. I consider this an advantage, as I can be in touch with my client directly and there's no buffer between us. I am a development-oriented guy who can see the big picture and understands business lingo too. I pick the 20% effort which will do 80% of your job. As for about some not so good feedback in my comments: Well no one is perfect, but at least I learn from my mistakes. Lessons learned: Do not take on more job than you can do. Always communicate with your client promptly. Take responsibility for all your deeds. That's about it. I know that lack of communication is the #1 killing of a (business) relationship. So you will not find me gone missing for days. I will always let you know about what's happening.  less
