Experiences

TrialReach
London, UK
At TrialReach I'm working as front-end developer. Mainly focused on single page application development including CSS, HTML and JavaScript coding.

Alkuvoima East
Helsinki, Finland / Varna, Bulgaria
Nowadays, everything lives in the browser. My main responsibility in the company is building flexible, modular and well tested JavaScript/HTMl/CSS based applications. Some of them require real time communication, so I have the luck to work with Node.js. Along with that I'm using Node.js to improve and speed up our workflow. Coding cross-browser web sites, I'm happy to say that I produce responsive apps.

Freelancer
At that time I was everything. I mean I was the sales and project manager. I did front-end and back-end development. I even design the sites of my clients. However most of my projects require solid JavaScript/ActionScript skills. It was interesting time, because the things started to change. The flash started dying and everyone wanted his product in pure HTML/CSS/JavaScript.

Knassar
Faroe Islands / Varna, Bulgaria
At the company I was responsible for the front-end development. 50% of my time went to JavaScript/HTML/CSS tasks and the other half was taken by Flash/Flex development. From time to time I code in PHP as well.

Design.BG Studios
Varna, Bulgaria
I started as graphic designer, but very soon I got new responsibilities. I had to slice my designs to perfect pixel HTML/CSS/JavaScript web applications. At that time Flash was still quite popular, so I started digging into ActionScript2/3. This gives me a very good base for my favorite language - JavaScript. You know, the both are based on ECMAScript.

Advertising Agency "EXTREME"
Varna, Bulgaria
My main job was to design print materials, but after few months I took care for the web sites requests. At that time we used mostly HTMl, JavaScript and Flash.
