Aleksandra Pawlik

Software Engineer

Biography

Backend software engineer with 6+ years building and evolving production systems in fintech. At JPMorgan Chase (Oct 2021 - Present) I ship and maintain services with a strong focus on reliability, observability, and developer experience using Git, Kubernetes, OOP, CI/CD, and SQL every day. Previously at Alfa Financial Software (2019 - 2021) I delivered new features and architectural improvements to asset-finance platforms in Java, with an emphasis on clean design and maintainability.

I value TDD, pair programming, and iterative delivery (habits formed at the Makers bootcamp), and I enjoy turning complex domain rules into simple, well-tested APIs and integrations.

If you think we should talk about opportunities in Oslo, please drop me a line. I'm excited to relocate and swap my London commute for Norwegian skis, trails, and a little Norwegian magic.
