I build and maintain scalable, high-performance web applications for small to medium-sized companies and startups needing custom solutions. Based between Germany and France, I work seamlessly with international teams across time zones. What I deliver: - Complex single-page applications with React/TypeScript - Component libraries and design systems built for scale - User-focused interfaces backed by UI/UX principles - Integration with external APIs (payment providers, internal data sources, public services) - Full-stack solutions when needed (Next.js, Node.js, Elixir, PostgreSQL) Experience highlights: - 8+ years specializing in React ecosystem with strong UI/UX design background - Principal Frontend Developer for enterprise identity & access management suite - Built compliance applications for major European financial institutions - Developed customizable onboarding platforms and admin dashboards with advanced data visualization - Fluent English communication with experience working across European and North American markets My approach: I work closely with you throughout the entire development process, with clear communication in English regardless of your location. We start with fast delivery of working, clickable prototypes to identify essential features early—ensuring we invest time where it matters most. This iterative approach means your budget goes toward functionality that drives real value, not unnecessary polish on features that won't be used. Available for: Small to medium projects (20-40 hours/week) including new applications, feature development for existing platforms, and modernization work. Ideal for startups and established companies needing senior-level frontend expertise without full-time commitment.
