    I offer my freelancing experience. Many of my jobs were to correct shoddy jobs of other freelancers. I have seen code of others; it was quite a mess. And I had to correct their egregious mistakes. I had to turn their ugly products into beauty. I now have the experience to know that the freelancing industry is rife with amateur developers, and I understand the frustration of clients because they can't get their job done. I have also seen clients doing a bad job putting their finished products together. I have seen my sterling code be run alongside the messy spaghetti code of others. I have seen my excellent web widgets on websites full of bugs. I believe that the experience that I now have on freelancing dynamics is my best strength, and if you are a client looking for a freelancer you should consider it well. I offer communication. Apart from knowing English fluently -and a couple more languages, I also aim for a sincere communication with the client. Even before a contract begins, I will make my terms clear and any technical difficulties that may occur, in order to prevent any misunderstandings. I offer a vast technical toolkit. I will not ever hesitate to learn a new skill or tool. For this reason I have built a huge and growing toolkit of many programming languages, frameworks, libraries etc. Many of the tools I have used on my freelancing I learned spontaneously. These tools have documentations for a reason after all; and I am good at studying it. I offer scientific backing. Having studied computer science, I know thoroughly the fundamentals of algorithms and software engineering. I apply this knowledge to my code for enhanced efficiency. I offer good code; readable, well commented, clean and consistent. I offer looks. My end products look good, and this is important because I mostly do web development.

    I just finished my Computer engineering diploma after 5 years of studying. My passion since I was 14 years old was building web sites starting out with Joomla and Wordpress. Later when i joined the University I became familiar with html, css, javascript, php and SQL. My biggest leap forward in the Web Developing world came when I was selected for a project building a Web Application for one of the University's systems, which was also my diploma thesis. Now my main skills extend from vue.js, javascript, react.js, html, scss to php, laravel , SQL.
