Gaganpreet Arora

Hi, I am Gaganpreet, a software engineer based in the Netherlands.

I have extensive experience on the backend, and with scalability, security and devops. As a product-minded engineer I love to approach projects both as a technical and business problems.

I’ve worked at companies of various sizes from small to big and right now I’m building stuff as an independent developer.
