Next.js Development Berlin
High-Performance Web Platforms, SaaS Products & Scalable Frontend Architecture for German Startups and Enterprises
Next.js has become the default framework for modern product engineering. But building a platform that is fast, stable, analytics-ready, GDPR-compliant and architected for real-world growth requires more than a basic React skillset. H-Studio is a Berlin-based engineering team specialised in Next.js 15, React 19, TypeScript, Supabase/PostgreSQL, and enterprise-grade backend integrations. We help startups and established companies build production-ready platforms — designed for performance, security, and long-term scalability.
Why companies in Berlin choose our Next.js engineering
Berlin's digital ecosystem moves fast. Products must ship quickly, scale predictably and perform under real traffic conditions. We build Next.js systems that combine speed, technical depth and operational reliability.
Production-ready Next.js architecture (not prototypes)
We design the full lifecycle architecture:
- •Edge-ready rendering with RSC
- •API routes built for reliability and load
- •Clean domain logic and modular structure
- •Analytics, funnels, event tracking
- •CI/CD pipelines for continuous releases
- •GDPR-compliant data flows and cookie logic
Your platform is ready for real users from day one — no rebuilds, no throwaway MVPs.
Performance as a core deliverable
Slow products don't scale.
We specialise in Core Web Vitals, Lighthouse optimisation and advanced bundling strategies:
- •LCP reduction for high-impact pages
- •Optimised image rendering with Next/Image
- •Route grouping and lazy loading
- •Server Components + Edge caching
- •Monitoring for long-term performance stability
Our Next.js systems consistently score 90–100 on mobile Lighthouse audits, even on content-heavy platforms.
Data-driven, analytics-ready from the first release
We integrate end-to-end analytics as part of the architecture:
- •Event-tracking (server-side + browser)
- •Conversion funnels
- •A/B experiments and retention metrics
- •ClickHouse/BigQuery pipelines
- •Metabase and custom dashboards for founders
This lets teams optimise onboarding, activation and revenue from the very first users.
Full backend support (Java, Node.js, microservices)
We are not a pure frontend studio. Our team includes senior backend engineers with 10+ years in Java microservices, Spring Boot, data streaming, API design and distributed systems. This enables us to deliver complete platforms, not isolated Next.js frontends.
