Christoffer Lilja
secure software architect in Jönköping, Sweden
I'm a seasoned .NET developer and technical architect based in Jönköping, Sweden, with over 16 years of experience designing and building secure, maintainable systems—primarily on the Microsoft stack and in Azure.
My passion lies in secure software development: from threat modeling and CI/CD pipelines to DevSecOps practices and infrastructure as code. I help teams deliver robust solutions by combining deep technical knowledge with a pragmatic approach to architecture, automation, and governance.
Whether mentoring security champions, modernizing legacy systems, or designing cloud-native platforms, I thrive in roles where I can ensure that security is built into every step of the development lifecycle.
Outside of work, I enjoy challenging myself—whether it's completing the 90km Vasaloppet or diving into the latest Microsoft certifications. I also love trail running, mountain biking, and orienteering.
