Rockstar🎓
Top SchoolJeremy Karlsson is a Senior Software Engineer with 13 years of experience specializing in high-performance web applications, progressive web apps, and cross-platform media playback. He played a central role modernizing TIDAL’s web and desktop clients—owning DRM-backed playback systems and migrating the stack to React, TypeScript, and Redux while maintaining microservices in Node.js and Golang. Comfortable across front- and back-end boundaries, he runs full-stack apps on Node, Deno and AWS Lambda and has hands-on experience with Web Components, PWAs and testing tooling like Playwright and Vitest. Jeremy blends pragmatic engineering with a performance-first mindset, having optimized user experience across web, desktop, Chromecast and TV integrations. Now at Arbeids- og velferdsdirektoratet after a long spell building product-grade media systems (and consulting on fiber infrastructure and legacy PHP/Golang stacks), he continues to bridge legacy and modern architectures. Based in Värmland, Sweden, he pairs production-level craft with a homesteader’s practical curiosity outside the keyboard.
