Senior🎓
Top SchoolJesper Kjeldgaard is a systems engineer with 14 years of hands-on experience building full-stack web applications, predominantly in Ruby on Rails, and currently working at Clearhaus. He has a strong startup pedigree—co-founding and serving as CTO for Grafik on Demand/Reklameskyen and shipping backend systems at Peanut to scale a social network for women. Jesper combines product-minded engineering (marketing automation, analytics, finance) with mobile and backend expertise, and has led small teams through redesigns, conversion optimization, and regulatory migrations. As a freelance senior engineer he focuses on delivering measurable business value from idea through deployment, and also codes in Go alongside Ruby. Based in Aarhus, Denmark, he pairs academic training in software engineering with practical leadership across multiple high-growth consumer platforms. Less obvious: he blends deep Rails instincts with experience maintaining mobile apps and back-office tooling, making him a pragmatic bridge between customer-facing features and reliable operations.
