Profile

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

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

I work in systems where state transitions, external side effects, and failure handling must stay understandable in production, because silent failures turn into real operational problems.

I build systems that hold up under load and over time, and improve how teams ship through testing, CI, and practical engineering standards.

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)
Integration Systems (webhooks, idempotency, retries, queued workflows designed for failure scenarios)
External API Reliability (handling partial failure, duplication, and inconsistent third-party behavior)
Testing for Integrations (feature tests, fixtures, queue assertions)
Data & Performance (MySQL, Redis, throughput control, data modeling)
System Design (maintainable architectures that stay understandable)
CI/CD & Delivery (GitHub Actions, fast feedback, safe releases)
AI-Assisted Engineering (faster iteration with verification and tests)
Docker / AWS / Linux (deployment and operational stability)

I worked with Odinn as a colleague during his time at Worksome. He proved his forward-thinking vision on embracing new technologies and ways of working, in particular taking a quite innovative position at trialing and adopting AI-assisted coding, and introducing AI innovations to amplify engineering capabilities. He cares deeply for the systemic health of the systems he works at, and keeps always an open and collaborative mindset in his approach to development. If you have the chance to work with Odinn - I recommend it!

Hans Peter Nielsen was CTO at Worksome during Odinn's time there. He highlights reliable delivery, stronger CI and test coverage, and leadership on Worksome’s webhook platform.

Hover to expand.

It is with great pleasure that I recommend Odinn. He is a highly motivated and self-driven backend engineer with deep expertise in Laravel.

During his time at Worksome, Odinn consistently delivered on complex projects, maintained ownership of his work from start to finish, and actively contributed to keeping our Continuous Integration (CI) green. He was instrumental in building out core platform areas and achieving higher test coverage, notably by owning significant parts of our test setup. Odinn also led our webhook functionality from inception to launch, and it now serves as a cornerstone of our integration suite. More recently, he demonstrated a big interest in leveraging AI tools, and actively impacted the direction and development of our Worksome Intelligence feature.

I strongly recommend Odinn for any web development engineering team focused on modern web development.

Odinn is one of the best engineers I’ve met at diving into complex, detail-oriented problems and getting to a clean, reliable solution. Even though his official role on my team was as a backend engineer, he was eager to jump in, learn, and help out across the full stack. He also made key contributions to engineering-wide test quality and infrastructure. I’ve also been impressed by his direct and proactive communication. He gives feedback early and often, and he’s always asking the right questions to better understand the problem being solved.
