Tadeusz in het kort

Focused on highly competitive markets the 14+ years of development experience have given me an edge in my development speed, agile approach and efficiency as my most valuable assets.

People call me positive minded and a problem solver. I like to get my hands dirty on the job. Finding the right solution is the greatest feeling in the world for me.

I am not afraid of failure. I think failure is part of my job. Yes it can give you some mixed emotions, we are still human after all. But I do strongly believe that if we don't try we will be stuck in the same place for many years.

I mainly focus on JAMSTACK architecture, Core Web Vitals & JavaScript / Typescript. I love to work with Node JS, Vue JS 2 & 3, Nuxt JS or even React / NEXT. I have a great passion for Javascript, Design Systems, DevOps Operations and SEO.

As a t-shaped developer I prefer working in cross-disciplined design and marketing teams. Continues
communication and feedback keeps the team aligned and motivated.

In my spare time I like to play games, work on my smart home or try out new techniques. I also like cycling & traveling.
