Hi, I am your new manager!

My name is Alexander, and I've had the pleasure of working at Blocket in various positions for the past 5 years. From being a front-end developer to a full-stack developer and a Tech Lead, I recently transitioned into management. As a manager, I strive to embody the ideal from a developer's point of view. I strongly believe that trust, autonomy, and transparency are the keys to creating a happy and efficient developer. I am passionate about technology and love participating in the technical discussion but my ambition is to empower developers to make any and all architectural and technical decisions themselves.

I'm really excited about this new team because it will be pioneering tech that will support the whole organisation in the future. It will be a true challenge to design and build the systems that carries this responsibility and when done right, they will make an impact for many years to come!
