Senior🎓
Top SchoolSteffen Martinsen is a Senior Software Engineer based in Oslo with 14 years of experience building front-end heavy web applications and full-stack solutions across consultancy, media, and in-house roles. He combines pragmatic engineering with a developer-first mindset—having run his own sole proprietorship since his teens and now founding Bitsi to pick projects that matter while contributing to open source and the community. Steffen’s background spans modern JavaScript frameworks, JAMstack migrations, and Microsoft/Azure ecosystems, plus hands-on DevOps and onboarding-focused tooling that saves teams time and cost. Known for humility, curiosity, and a love of coffee, he blends practical problem-solving with clear communication and mentoring as a former Frontend Community Lead. An unexpected thread through his career is early media and design work, which informs his attention to UX and product polish.
