What I'm looking for

I am looking for a company that wants to grow fast but does not neglect quality

I specialize in the development of web applications that simplify all kinds of tasks, both professionally and as a personal passion. With over a decade of experience and a strong aptitude for logical thinking I excel at creating robust and sustainable applications with well-established architecture. As an avid enthusiast of machine learning I am particularly drawn to opportunities with small to medium-sized companies and startups where I can make a significant difference. Vegan btw.
