A focused set of products where I owned the path from concept to working system—across product decisions, experience design, and engineering.

Pullmark connects digital pack openings to company-owned physical inventory, customer ownership decisions, store credit and refunds, and eventual fulfillment. I own the product and engineering across the consumer experience and operational tooling.

About

Builder across the whole product.

I'm a Stockholm-based full-stack engineer with professional experience since 2017. I'm happiest owning the difficult middle between an idea and a product that works: product decisions, interaction design, frontend, backend, data, integrations, deployment, and the thousand details around them.

I started building interfaces with Java Swing in 2010 and making websites for clients a few years later. That early curiosity never left; the scope just grew. Today I build end-to-end systems across consumer products, marketplaces, personal tools, and AI-assisted experiences.

  • Web and mobile frontends
  • Backend and data systems
  • Authentication and integrations
  • AI-assisted product features
  • Deployment and operations

Have something ambitious in mind?

Let's build something real.

I'm always interested in thoughtful products, difficult systems, and collaborations where seeing the whole picture matters.
