Spring Boot Development
Enterprise-Grade Backend Engineering, Microservices Architecture & High-Performance Java Systems for Businesses in Germany
Spring Boot remains one of the most reliable, scalable and secure backend frameworks in modern enterprise software. At H-Studio, we build high-load, distributed and mission-critical systems using Spring Boot, Java 17/21, event-driven architectures and cloud-native tooling. Our engineering team in Berlin has over a decade of experience delivering backend platforms for fintech, telecom, banking, real estate, SaaS and enterprise digital products. We build backends that are stable, fast, fault tolerant and ready for real-world scale.
Why Spring Boot for Modern Products
Spring Boot is the foundation of countless enterprise systems because it provides:
- •predictable performance under load
- •mature tooling for distributed systems
- •strong security and authentication standards
- •high reliability for financial, operational and data-intensive products
- •flexibility to integrate with any modern frontend (React, Next.js, mobile, IoT)
- •seamless compatibility with cloud platforms (AWS, GCP, Azure, Hetzner)
We take these strengths further by combining them with modern DevOps, observability and microservice patterns.
Spring Boot Development Services
1. Backend Architecture & System Design
We design backends that support long-term growth:
- •modular architecture
- •clean domain logic (DDD where applicable)
- •asynchronous processing
- •high-availability clusters
- •multi-service orchestration
- •stable API contracts
Your backend becomes a predictable, scalable core of your digital product.
2. Microservices Development & Event-Driven Systems
We build distributed systems using:
- •Spring Boot microservices
- •Kafka / RabbitMQ event streams
- •asynchronous communication
- •fault-tolerant service interactions
- •idempotent processing & retry logic
- •monitoring & alerting at scale
Perfect for fintech, operations platforms, logistics, marketplaces and any product requiring high throughput.
3. High-Load Systems & Performance Engineering
We specialise in systems that must handle millions of events or requests. Our expertise includes:
- •thread & memory optimisation
- •database performance tuning (PostgreSQL, Oracle, MySQL)
- •caching layers (Redis)
- •rate limiting
- •performance monitoring
- •JVM optimisation
- •load testing & capacity planning
This ensures your system performs reliably even under significant real-world demand.
4. API Engineering (REST, GraphQL, gRPC)
We build robust, secure APIs used by frontend apps, partners, mobile apps and internal tools:
- •versioned REST APIs
- •gRPC for high-performance internal communication
- •GraphQL where flexibility is essential
- •authentication & authorization
- •schema governance
- •validation & error handling
Our APIs are designed to remain stable as your product evolves.
5. Database Architecture & Data Workflows
We architect reliable data systems:
- •PostgreSQL, Oracle, MySQL
- •schema design & migrations
- •distributed transactions
- •data streaming & ETL
- •analytics-ready event logs
Your data becomes consistent, queryable and ready for analytics growth.
6. Cloud-Native Spring Boot on Kubernetes
We deploy large Spring Boot systems on:
- •Kubernetes (K8s)
- •AWS ECS/EKS
- •GCP GKE
- •Azure
- •Hetzner private clusters
With:
- •autoscaling
- •zero-downtime deployments
- •observability (Prometheus, Grafana, Loki)
- •CI/CD pipelines
- •service meshes
This gives you predictable releases, reliability and operational stability.
7. Migration & Modernisation
We help teams modernise legacy Java applications:
- •migration to Spring Boot
- •restructuring monoliths into modular monoliths or microservices
- •upgrading Java versions
- •replacing outdated libraries
- •improving performance & reliability
- •redesigning data models
Without risking downtime or breaking existing business logic.

FAQ
Do you work with Java 17 and Java 21?
Yes — we specialize in Java 17/21, Spring Boot 3.x, and modern Java features including records, pattern matching, and virtual threads. We also help teams migrate from older Java versions.
Can you build microservices architectures?
Yes — we design and implement microservices using Spring Boot, event-driven patterns (Kafka, RabbitMQ), service discovery, and distributed tracing. We also help teams migrate from monoliths to microservices.
Do you deploy on Kubernetes?
Yes — we deploy Spring Boot applications on Kubernetes (K8s), AWS EKS, GCP GKE, Azure AKS, and Hetzner clusters with autoscaling, zero-downtime deployments, and full observability.
What about database performance?
We optimize database performance for PostgreSQL, Oracle, MySQL, and other databases. This includes query optimization, connection pooling, caching strategies, and distributed transaction management.
Can you help migrate legacy Java systems?
Yes — we help teams migrate legacy Java applications to Spring Boot, modernize architectures, upgrade Java versions, and improve performance without downtime.
