know who i'm

The beginning of origin story starts with web development dating back to 2010. From the end of 2018 transitioned into the area of Engineering.

I am passionate about OpenSource and the world of Linux. Throughout the years I worked with various organizations, from small SME's to Fortune 500 companies, on a wide variety of projects.

Taking pride in delivering quality over quantity, instead of overpromising and underdelivering I prioritize service quality.
