Curriculum Vitae

Portrait of Odinn Adalsteinsson

Profile

Senior Software Engineer with 20+ years of experience building backend systems, integrations, and developer tooling.

I design and own integrations end to end: underdocumented third-party APIs, custom authentication, webhook delivery, queued workflows, deduplication, and idempotent processing.

I make those systems easier to change through tests, CI, clear boundaries, and delivery habits that keep production boring in the useful way. Based in Copenhagen; open to remote roles across Europe/EMEA.

Core Competencies

The practical mix is stronger than the title makes it look.

  • Laravel / PHP (logic-heavy backend systems, APIs, integrations, developer tooling)
  • Integration Systems (webhooks, idempotency, retries, queued workflows built for failure)
  • External API Reliability (partial failure, duplication, and inconsistent third-party behavior)
  • Testing for Integrations (feature tests, fixtures, queue assertions, failure paths)
  • Data & Performance (MySQL, Redis, throughput control, data modeling)
  • CI/CD & Delivery (GitHub Actions, fast feedback, safe releases)

    • Improved delivery confidence through stronger feature tests, CI discipline, and clearer patterns for safe changes.
    • Worked across backend and frontend boundaries so delivery did not stall on handoffs or fuzzy ownership.
