I'm Stian, a passionate full stack web developer based in Norway, currently crafting innovative solutions at Sleipner Motor. With a Bachelor's degree in Computer Science and over three years of hands-on experience from professional roles and personal projects, I thrive at the intersection of design and backend engineering.
My journey into technology began in my father's hobby room, where tinkering with computers sparked a lifelong fascination. Today that fascination has grown into my own company, Larsen Utvikling, where I design and ship my own products: native macOS apps like Station, FrameSnapper and dotViewer, the evidence-based CV tool Spiss, and DBHost - my honest, personal MVP for managed PostgreSQL hosting. Most recently I relaunched Tinify.dev with a public API, account plans, credits, and a complete redesign. I enjoy creating tools that simplify and enhance everyday tasks. When I'm not coding, I cherish time at home with my little family, binge-watching movies or brainstorming the next web application.
Driven by ambition, creativity, and a love for problem-solving, I'm dedicated to building user-friendly, high-performance applications that make a real difference. Let's connect and create something amazing together!
