SOFTWARE×PLATFORM×DATA×LEADERSHIP

From problemto production.

Built on automation, coffee and stubbornness.

I'm Bjarni Kristján Leifsson — I've never been interested in just one layer of technology. I like understanding the whole system: the software, infrastructure, people, product, operations, risks, costs and decisions.

Portrait of Bjarni Kristján Leifsson

Ideas are easy. Making them real is the interesting part.

Beyond the code

Engineering, infrastructure, operations and the decisions around them.

  1. 01

    BUILD

    Software, platforms, integrations and tooling.

    Full-stack development across C#/.NET, Node.js, Python and Angular — plus the architecture and tooling improvements that make a codebase easier to work in.

  2. 02

    SHIP

    CI/CD, deployment workflows, containers and production delivery.

    Robust CI/CD pipelines, improved deployment processes, and development workflows improved across teams — not just my own.

  3. 03

    OPERATE

    Infrastructure, platform stability, IT operations and reliability.

    Infrastructure and IT operations ownership, monitoring, platform stability and operational continuity — resolving issues before they became visible to the wider organization.

  4. 04

    LEAD

    Architecture, vendors, costs, risks, documentation and decisions.

    Vendor coordination, infrastructure purchasing and billing oversight, technical documentation, risk identification, and communication with technical and non-technical stakeholders.
