    Information Technology and Security Expert

    Romania - Last active: 4 months ago - Tests: 8

    I enjoy investigating a multitude of subjects, for example when I was 14 I started to learn PHP, three weeks after I was programming an internal chat system for a casino in Holland. Afterwards, small web-related projects followed; when I was 16-17 I was hired as a company administrator in the fields of IT Security, Computers and Network administration/installation, CCTV surveillance, PBX administration and Access Control. At 18, I've started to research the field of reverse software engineering and subsequently developed web-crawlers/spiders as well as playing around with various programming languages. Soon after, I have found interest in the field of Ethical Hacking and developed applications regarding protocols such as POP3, SMTP, FTP and I have also conducted research on how the aforementioned protocols can be correlated in order to subdue RDP-enabled servers. To cut the story short, I have a diverse interest which spans a multitude of IT related fields.

My native language is spanish, but I feel comfortable reading and writing english too. With more than 30 years of hands-on experience, I've worked on many different projects, creating, for example, real-time systems for car parks, the software used in the distribution of Yellow Pages throughout a large part of Spain, logistic software used by Fagor Electrodomestics in his supply chain, a cloud based documental software called 'MdO' in use by hundreds of customers and a large number of specific applications and websites for various professional sectors such as notaries, agencies, medical centers, sports centers,etc. If you need a senior multidisciplinary specialist with high skills and experience on several developing technologies, web or desktop programming, Wordpress, Prestashop or system hosting and management, you've find it. I'll be glad to talk to you, listen to your needs and provide a solution if I think I am the right person to do it.

    Hi, I'm Angjelko, you can call me Jack. I'm 20 years old, technology lover, but to be honest, I haven't finished any university or went to IT School I studied High School Medicine, but please don't stop keep reading... all what I accomplished so far was thanks to the Internet, and my determination to succeed, to make the "Web World" and "Every Day Life" a better place, you may think yes but you haven't go to any IT School, yes, but if you look on the bright side, most of the brains that lead the technology towards, haven't wen't to an university and some of them haven't finished high school, like Bill Gates, Mark Zuckerberg, Steve Jobs and etc. But they all had one thing, the desire to create something better, and I have the same desire, to create something that is: crazy, scientific, impossible, but nothing is impossible, its only its not possible at that moment, but trying hard and not giving up, there will be a moment where that thing will be possible, we are humans, and we learn from our mistakes. My primary target is not to earn Money, but to be recognized, even I become a Billionaire some day I will still work, because its boring if you don't work, I started studying HTML5, CSS3 and JavaScript last year right after finishing High School Medicine, from W3Schools to Debugging and replicating popular Websites and to becoming a Web and Phonegap Developer, thanks to my hard work and thanks to the Internet I am what I am now...a Great Web Designer, Web Developer, and Expert in Phonegap App and Game Developing. I'm also a Freelancer, working at Freelancer.com, I just started and so far I'm doing great, I have 8 projects so far completed, and my Rating is 5.0. That's because I'm honest person, and I only Bid on projects that I'm sure that I can and I will accomplish..because bidding on project that I can't accomplish will only give me bad rating and that's not my target. As I said I'm a Web Developer, I can Design and Program: Websites, Web Apps I can build Mobile and Desktop Apps and Games for one of the most popular Platforms like: Android, iOS, Windows Phone, Blackberry, Windows 8, Ubuntu, I can even develop for the newest platforms, like Firefox OS and Tizen, all that thanks to the Phonegap, also known as Cordova Framework by Adobe and CocoonJS by Ludei. I can do both Logic and Design because, everything I imagine in my head I bringing to life wherever its a Design or Programming, from the most loved Design I would like to work are the Flat Design, the Minimalist Design, the Material Design and the iOS7 and iOS8 Design...Thanks for Reading I'm happy to code for you... PS. I love Fantasy....so there isn't impossible in my world ^_^ Regards, Jack.
