What I'm looking for

I'm looking for remote frontend work where I can own complex product features from Figma through release, build durable design systems, and collaborate asynchronously across distributed teams.

At KT Informatik, I own customer-facing React, Next.js, TypeScript, and Tailwind CSS features from Figma design through production release. I’ve built and maintain a shared design system and component library used across seven live products.

I architect interfaces for multi-tenant permissions, multi-state approval workflows, dashboards with simultaneous data feeds, and multilingual RTL experiences. For SocialCrew, I built an approval queue, scheduling calendar, unified real-time inbox, and component-level role-based access for a product operating six social networks from one queue.

I also built shared locale-routed components and direction-aware layouts for two news platforms serving seven language editions, avoiding seven separate codebases. Across B2B and SaaS platforms, I’ve delivered SEO-focused Next.js frontends alongside Node.js and Express REST APIs.

I treat performance, accessibility, testing, and review as part of delivery: improving Core Web Vitals, building semantic keyboard-accessible interfaces, writing Jest and React Testing Library coverage, and mentoring junior developers.
