From 2014 I'm involved in creating my dream project which is a web platform that connect Asian comic creators with Western readers. Together with our Japanese friends we are carving our idea. Mangaido is a comic series translation platform.

At the beginning of 2016 I moved to Brussels and started working in Stepstone - well known job board company, as a Front-end Developer. Later on I started working also as a Back-end guy. The most important experience from that time was working with team in Agile/SCRUM environment. I was working on new version of search application that is used by recruiters all over the world. The biggest challenge was creating one application that is used by clients with different preferences and having lots of complicated facets making this search engine very smart tool. The front-end was done mostly in Angular.js and back-end in ColdFusion.

fullDive.jp was a creative agency where me and my friends where working on different, mostly web oriented, projects. I used my skills mostly as a web developer, designer and a Google Trusted Photographer. Often we had to cooperate with other freelance web developers and my role was to plan, split the work and take care of communication layer as what I consider is a core of successful IT projects. During this time we created lots of websites, graphics and Street View Tours for our clients.

I was working in Wrzosek.pl to create and maintain IT infrastructure. Beside taking care of the website, I was responsible for creating and maintaining application that was scraping and categorizing real estate offers from different other websites and sending new offers to agents based on their personal preferences. Thanks to this application company was always up to date with everything that was happening on the market.
