Svea Ekonomi

Software Engineer, TDD mentor 2017-10 2018-04

Context

Svea Ekonomi was my first assignment as a freelancer. I joined the team responsible for Svea Checkout, a payment solution being rolled out across Sweden, Norway, and Finland. The work combined backend development with a strong focus on engineering practices, particularly around testing and documentation. I also took on a mentoring role, helping the team strengthen its approach to TDD and executable specifications.

Work

Backend Development

• Built and extended APIs using C# and ASP.NET Web API
• Applied CQRS patterns to separate read and write concerns
• Worked with Entity Framework for data access
• Contributed to deployment workflows using Octopus Deploy

  Engineering Practices

• Introduced and coached test‑driven development to improve code quality and confidence
• Rewrote existing tests as executable specifications to make intent clearer and behavior easier to understand
• Improved API documentation by generating most of it automatically, reducing manual effort and inconsistencies
• Helped strengthen the team’s continuous integration routines

Outcome

• Contributed to the rollout of Svea Checkout across multiple Nordic markets
• Improved the clarity and maintainability of the test suite through executable specifications
• Reduced documentation drift by automating large parts of the API documentation
• Supported the team in adopting more consistent and sustainable engineering practices

Reflection

This assignment marked the beginning of my freelance career and set the tone for how I like to work: combining hands‑on engineering with a focus on clarity, testing, and sustainable development practices. It was a chance to contribute to a real‑world payment product while helping a team level up its approach to quality.
