Next.js Development
High-Performance Web Platforms, SaaS Products & Scalable Frontend Architecture
Next.js has become one of the leading frameworks for modern product engineering. But building a platform that is fast, stable, analytics-ready, aligned with GDPR requirements, and architected for real-world growth requires more than a basic React skillset. H-Studio is an engineering team specialized 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 teams choose our Next.js engineering
Modern product teams move 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 designed for real users from day one, with an architecture that minimizes early rework.
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 enables teams to analyse onboarding, activation, and revenue signals early in the product lifecycle.
Full backend support (Java, Node.js, microservices)
We are not a pure frontend studio. Our team includes senior backend engineers with extensive experience in Java microservices, Spring Boot, data streaming, API design, and distributed systems. This enables us to deliver complete platforms, not isolated Next.js frontends.
Performance as a core deliverable
Performance issues can limit a product's ability to 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 are optimized to achieve strong Lighthouse and Core Web Vitals results, including on content-heavy platforms.
