What I'm looking for

I'm seeking senior frontend roles (remote or hybrid) to lead Angular-based projects, build scalable component libraries and design systems, improve testing/CI pipelines, and collaborate across teams to deliver high-impact products.

I am a passionate software engineer with 12 years' experience and seven years focused on Angular (2+), RxJS and testing practices. I build scalable frontend architectures, reusable component libraries and design systems, and I bring fullstack thinking that improves cross-team collaboration.

At Accountfy I delivered an embedded PowerPoint data-link feature, led the Debt Control module from scratch, refactored legacy financial modules and increased test coverage to reduce production bugs. Previously I built internal systems and CI/CD pipelines at Scania and hold an AWS Certified Cloud Practitioner credential.
