My technical skills encompass a wide range of technologies due to the rapidly evolving nature of the web. Throughout my career, I have worked with various tools and frameworks. I have experience with Flash and ActionScript 2/3, LAMP projects, jQuery, Backbone, ExtJS, MooTools. I have experimented with Angular, Ember, and Knockout, but my preferred framework is React and its ecosystem. Last years I'm focusing on building everything with JavaScript/TypeScript. I feel comfortable working on the both back-end and front-end.

Over the years, I have worked on diverse projects, gaining intermediate knowledge in Unix and server administration. I have configured Apache and nginx and have worked with both SQL and NoSQL databases. Recently, I have been using Docker and Kubernetes within Google's cloud platform. I am proficient in using Git and various command-line instruments to automate workflows.

It's worth mentioning that my career started as a graphic designer using tools like Photoshop and CorelDRAW. I gradually transitioned to "web design" and then shifted towards programming roles.
