Über mich

Hello, My name is J. a seasoned full stack engineer focusing on frontend development and project management.
As a passionate engineer who spent most of my career at startups, I am always open to positions at startups.
Opportunities at startups gave me much more opportunities, I was able to play multiple roles in the team including SEO specialist, Data engineer, Devops, Data Analytics, Database Engineer ...
It gave me lots of chances to communicate all of team members frequently and I was able to participate in taking technical decisions.
I have been growing up rapidly, not only programming skills but crucial skills like turning business model into technical infrastructure and solutions.
Also I am open to positions at medium-scale companies where I can work in very organized team and where I can mentor the others.
Mentoring especially pair programming is what I like to do when I mentor the others.
I would like to hear from you soon.
Best regards
