I build scalable, accessible frontend applications with React, Vue, TypeScript, and enterprise SAPUI5 components.
GermanyWhat I'm looking for
I'm building production-grade web applications at PROMOS consult, creating reusable React components, custom hooks, and responsive interfaces from Figma designs.
I connect frontend applications to backend services through Fetch API and service layers, while integrating React components with SAPUI5 modules and OData-based enterprise systems.
I improve reliability through Vitest, React Testing Library, TestCafe, CI coverage checks, and SonarQube analysis. I also use Zustand, Storybook, SCSS, CSS Modules, semantic HTML, and accessibility practices to keep interfaces maintainable and inclusive.
Before PROMOS consult, I worked as a frontend developer at Tiplu GmbH and K&W Media Consulting GmbH, delivering work with React, Vue.js, JavaScript, Ruby on Rails, ASP.NET, and Git-based code reviews. I’m motivated by new technologies, stronger codebases, and practical solutions that perform well.
