Sergiu Dan Petru Barbus

Sergiu Dan Petru Barbus Agency Contractor

Backend developer / Database expert

Romania - Tests: 7 - Portfolio: 21

I have been working on the backend part of some major systems and RDBMS (Oracle 9i&10g, MySql) for more then 10 years now, being responsible with the maintenance and administration of some medium size servers (database and application servers), implementing security and backup/recovery policies, developing a large amount of applications for internal use (within the company). I have turned to freelancing a while ago because I wanted to be my own time manager, to be able to grow and learn in a more independent way, to choose what to focus on and where to invest my time and knowledge. I must say it was one of the best decisions I have made so far... I am more then pleased with what I got to work on, with my clients and with the way I am able to learn new things or to get more specialized in the ones I already know. I am focusing on web related elements, working with HTML, CSS, PHP, Apache, JavaScript. I like to work with strong standards, thus I prefer MVC based PHP frameworks (like Symfony), standardized HTML5 templates (like Bootstrap) and JS libraries (like jQuery). All the projects I have been involved in were a success, my clients being more then satisfied with the delivered results. I want to apply my experience as a web developer and database designer/analyst/administrator as well as my knowledge of software analysis and development. I am particularly interested in web related backend projects, built on LAMP stack with MVC pattern based frameworks and backed up with MySql databases.
