About Mikael

Your platform needs to evolve — aging architecture, scaling bottlenecks, or AI capabilities that need to be built right, not bolted on.

I step in as a Software Architect or Interim Tech Lead: I assess fast, prioritize what matters, and deliver — hands-on, not just advisory.

20+ years building backend systems at scale. At Wallbox I built the Installations platform from zero to €3M revenue across 12 countries. At Meeting Lawyers I modernized a 10-year-old legacy system while doubling company revenue. At eKlevo I built AI-integrated workflows in production — OpenAI API, streaming responses, vendor abstraction, cost controls.

Clean architecture. Working software. No lengthy reports.
