Summary
Full-stack developer with seven years of experience building and evolving business-critical web services in the TypeScript ecosystem. My focus is React and Next.js, where I have worked on products used by hundreds of thousands of people every day — including Klarna's checkout, Spotify's partner portal and Royal Design's e-commerce.
I am used to stepping into existing codebases and becoming productive quickly, but also to taking technical ownership from scratch: architecture, cloud setup and deployment. I have built IoT platforms on both AWS and Azure, set up automated testing and accessibility pipelines, and led frontend teams, including client contact and task planning.
I also bring several years of experience in communication and ownership from an earlier role as a team leader, which shows in how closely I work with clients, designers and product owners.
Co-founder
I am one of the founders of Flowbic AB, a consultancy in Kalmar that I have helped build from the start, and I take my assignments through the company. Alongside development, that means quotes, contracts and client contact — I answer for both the technology and the terms without going through anyone else, and if more developers are needed, there are colleagues in-house. flowbic.se

What I take ownership of
Stepping into an unfamiliar codebase
Used to becoming productive quickly in large existing systems — ByggHemma, Klarna and Royal Design were all live products with their own conventions.
Technical ownership from scratch
Architecture, cloud setup and deployment. DeepGrid, eSmart, Märka and Top Formula were built from choice of stack to production.
Accessibility for real
Technical lead for EAA/WCAG 2.0 compliance at Royal Design, with automated accessibility tests in CI/CD instead of one-off efforts.
Leading and communicating
Frontend lead with client contact and task planning, background as a team leader. Works closely with clients, designers and product owners.
Working with AI
- I use Claude Code and Cursor daily as an integrated part of my workflow, from debugging unfamiliar codebases to implementation.
- Used to reviewing and quality-assuring AI-generated code rather than trusting it — the same standards for test coverage and readability as for my own code.
- Part of a team that delivers AI integrations.
Selected projects
10 projects that show the range: business-critical frontend at Klarna and Spotify, technical ownership of accessibility at Royal Design, and cloud platforms built from scratch.
