Alexandru Marinescu

Alexandru Marinescu Agency Contractor

Freelance web developer / programmer with sysadmin experience

Romania - Tests: 10 - Portfolio: 3

I enjoy programming, building websites and fixing stuff. In the past 4 years I have worked with PHP/Codeigniter, MySQL, WordPress and Prestashop. Recently I started to learn Ruby/Rails building an awesome web app so I'd like to work more on some beginner-level Ruby/Rails/Sinatra projects to improve my skills. Also, I had to learn Linux by myself to deploy two apps in production. I can install basic services, do monitoring, improve default security. I'm interested in jobs that require programming skills - I know how to work with Photoshop for basic image manipulation but I don't have design talent.

United States - Tests: 3 - Portfolio: 3

I design applications for businesses and individuals using a combination of Ruby Development and Web Development. I am a creative researcher at heart, who loves the process of gathering information followed by insightful problem solving. Being an avid reader and data junkie, I believe simple answers work best, but must be found amidst the resources you gather. From the lectures I give at Whitman School of Business, to the activities that occupy my days, three characteristics stand out to each person I encounter: Intensity, Insight, Passion.

Juan Passadore

Web Developer

Brazil - Tests: 5

In the 10+ years I've been doing web development I've accumulated a good amount of knowledge in a wide range of related technologies and tools. Having always worked in small teams I've had the luck of staying dynamic and be able to move forward and experiment all the new and shiny stuff. I have extensive experience (6+ years) in javascript (both client and server side) and PHP, MySQL, MongoDB and everything that makes a website really (HTML, CSS, Less, Bootstrap, etc). To a lesser extent I've worked with Ruby, Perl and Python. I'm an open source fan. Linux being my desktop OS since before my web development forays. KDE > Gnome, Vim > emacs. And since I'm opinionating I say: "javascript should be written with semicolons!" What I care about most is in building long lasting and meaningful relationships with the client. I aim to continue learning and progressing in my career while providing outstanding value.
