I build enterprise Angular applications for complex business workflows.

Poland
Message

I've built and maintained enterprise Angular applications at Alcon for invoicing, shipping, customer service, and product management. I contributed to Angular upgrades from version 13 to 19 in an Nx monorepo and integrated frontend modules with REST APIs.

At Brightstar, I developed Angular and TypeScript features for a multi-market product, adapting processes and configuration across four countries. I work closely with backend developers, QA, and product managers to resolve integration issues and deliver reliable features.

I've also rebuilt a company website at Kamela using Angular 19, standalone components, lazy loading, SSR, and optimistic UI patterns. My work includes RxJS, NgRx, Angular Material, testing with Jest, Karma, and Cypress, plus AI-assisted development with Claude and GitHub Copilot.
