About

Berlin ReactJS development agency specializing in web applications, React Native mobile apps, and headless CMS websites.

Who They Work With

FinTech and B2B SaaS teams needing senior React/TypeScript engineers to embed or build headless-CMS sites.

Engagements:Project-basedEmbedded teams

Based on 16 documented clients · verified Jul 2026

Our Take

Makers' Den publishes 16+ case studies, most with named client testimonials, split between year-long embedded engineering (Klarna's Custom Solutions team, OLX's moderation frontend, Wonder) and fixed-scope headless-CMS builds (Shift4, Pexip, CEPRES, Perk). Klarna's Head of Global Enterprise Custom Solutions and OLX's Head of Product both endorse the work.

This is a development agency—engagements center on React/TypeScript/Node engineering rather than UX design or research, and design is often handled by a client-side or separate partner (as on MeisterTask and CEPRES).

The weaker fit is a primary need for UX design or user research: this is a senior-engineering shop (Top ReactJS Developers Germany 2025), strongest embedding into product teams or building headless-CMS sites.

Key strengths

  • Klarna case documents a full-year embedded engagement building custom payment solutions—testimonial from Head of Global Enterprise Custom Solutions confirms engineering quality
  • MeisterTask case shows structured sprint-based delivery with Storyblok CMS—testimonial praises on-time delivery, scope management, and rigorous bug testing
  • Verifiable Berlin office (Germanistr. 1A) with Top ReactJS Developers Germany 2025 on Clutch

Good to know

  • This is a development agency—UX/UI design is not a visible service; the MeisterTask project used a separate design partner for wireframes and design
  • Klarna engagement was team augmentation (staff aug), not project delivery—clarify which engagement model applies to your project
