About Jan Brennenstuhl

Hi. My name is Jan Brennenstuhl, I live and work in Berlin Germany, where I was born and raised. I am a product-minded software engineer, web security enthusiast & clean code artist with a huge interest in interdisciplinary software development and engineering leadership. I am a big fan of cycling sports, coffee & hiking.

I currently work for in Berlin as principal engineer, mainly focussing on balancing security with friction for our customers. I modernize customer identity and access management solutions and engineer single sign-on (SSO) solutions.

I’ve worked as a software engineer and lead on e-commerce funnels, rule engines, cloud strategies, IAM and SSO solutions, REST APIs, system integrations, technology research, legacy migrations, decommissioning projects and modularizing monolithic systems - various things, mostly in eCommerce and security though. I practiced software archaeology more than I set up greenfield web services.

I am an Internet standards enthusiast, who values open source and open formats over custom builds. For me, quality software products are created best by small teams of product-minded engineers with a narrow, well-defined business scope and a clear vision. I’m especially passionate about leading engineers as well as creating and operating reliable, secure and maintainable software products.

I hold a M.Sc. in Computer Science from the University of Potsdam, where I completed my thesis on “Certificate Management in the Cloud for Authentication in university Environment”. I’ve also studied Media Informatics at the Beuth University of Applied Sciences in Berlin.
