Über Angela

I'm a senior frontend engineer with 10 years of experience building and scaling product-focused web applications across startups and established platforms.

My work spans the full frontend lifecycle, from architecting scalable component libraries and design systems to leading cross-functional teams and owning the technical quality of consumer web applications.

I've held senior and lead roles at Care.com, one of the world's largest care marketplaces, and travel-tech startup Tourlane, collaborating closely with product and design teams to build scalable, user-focused web applications. I bring both the technical depth to make sound architectural decisions and the communication skills to work effectively across teams and with non-technical stakeholders.

What I bring to a project:
  • Strong React, TypeScript, Next.js and GraphQL expertise
  • Experience building and maintaining UI component libraries and design systems
  • Cross-functional collaboration and stakeholder communication
  • Technical leadership: code quality, mentoring and process improvement
  • A product mindset: UX-driven development, experimentation and analytics

Based in Germany, I work remotely with occasional availability for on-site days in Berlin.
