Filip Konkowski

Software Engineer

Biography

I'm a backend software engineer focused on building reliable APIs and integrations for fintech and SaaS products. My primary toolkit includes Kotlin and Java (Spring Boot), with additional experience in Python and PHP, AWS, Terraform, and CI/CD practices.

I'm excited to relocate from London to Oslo and actively exploring opportunities to help teams ship scalable, maintainable systems. Ready to swap my London commute for Norwegian skis, trails, and a little Norwegian magic.
