Java & Spring Development Services
Eurisko offers world-class offshore Java and Spring development services designed to help businesses build robust, future-proof backend systems. With deep expertise in Spring Boot, microservices, API development and cloud-native architectures, our teams deliver enterprise-grade solutions that are both high-performing and highly maintainable.
Whether you are launching a greenfield project or modernizing existing infrastructure, Eurisko combines technical excellence, agile delivery and cost-effective execution to bring your backend vision to life, at scale and with speed.
Backends built to run for a decade.
Java and Spring sit behind the software that cannot fail: banking integrations, payment flows, government platforms and the APIs every mobile app depends on. Eurisko’s Java engineers build and run these backends with Spring Boot, Spring Cloud and the wider Spring ecosystem.
An offshore Java squad from Eurisko works as an extension of your engineering team: in your repositories, under your coding standards, with a delivery lead accountable for every sprint.
Why choose Eurisko for Java and Spring development?
Java, one of the most mature and widely adopted programming languages, combined with the powerful and modular Spring framework, offers a future-proof foundation for backend development. We leverage the Java/Spring ecosystem to engineer high-performance backend solutions that are flexible, testable and built to evolve with your business.
Proven expertise across complex architectures
Scalable, secure backend systems in Java, Spring Boot and microservices: from enterprise banking platforms to API-first SaaS products.
Agile delivery with dedicated teams
Dedicated Java squads that integrate with your workflows: faster release cycles, continuous feedback and on-demand scalability.
Quality, security & maintainability
Strict coding standards, CI/CD, test coverage with JUnit and Mockito, and Spring Security / OAuth2 / JWT best practices.
Flexible engagement, cost efficiency
Full project ownership, team augmentation or co-creation: offshore economics without compromising engineering quality.
The Spring ecosystem, end to end.
Spring Boot services, Spring Security for OAuth2, OpenID Connect and JWT, Spring Data over PostgreSQL, Oracle or MongoDB, and Spring Cloud for configuration, gateways and resilience.
Event-driven work runs on Kafka or RabbitMQ, caching on Redis, and every service ships as a container through CI/CD to Kubernetes, on-premises or in the cloud.
Digital channels Java and Spring power best.
From content-rich portals to IoT command-and-control, the Java/Spring stack carries some of the heaviest workloads in enterprise software.
Web portals & enterprise sites
Complex, high-traffic portals with Spring MVC or React/Angular front ends, strong session management and CMS integration.
Mobile API backends
Spring Boot REST and GraphQL backends serving native and cross-platform apps with secure authentication and real-time data.
Public & private APIs
Well-documented, monitored APIs with security and throttling out of the box: critical for API-first architectures.
Admin panels & back office
Role-based internal tools, reporting dashboards and workflow automation on Spring’s security and data layers.
IoT & device platforms
Telemetry ingestion, rule-based alerting and MQTT/Kafka integration with Spring Cloud Stream.
Messaging & real-time systems
WebSocket support, asynchronous processing and message brokers like RabbitMQ and Kafka.
Every merge passes the same gates.
Before any change merges it passes unit and integration tests with JUnit, Mockito and Testcontainers, static analysis, a dependency scan and a peer review. The pipeline enforces it, so quality never depends on a good day.
Security is designed in: Spring Security with OAuth2 and JWT, secrets kept out of code, and audit-friendly logging for regulated environments such as banking and government.
A Java squad that works as yours.
You approve every engineer by CV before they join, and the squad stays yours: the same people, on your roadmap, inside your rituals. Beirut’s working day overlaps Europe and the Gulf, so questions get answered the same day.
The bench behind each squad is trained by Eurisko Academy, which teaches Java and Spring Boot, so scaling up never means starting from scratch.
A process built on evidence.
Define the team
We map your roadmap to roles and propose a named squad with CVs, no anonymous benches.
Trial sprint
A paid two-week sprint on real work, so you judge the team on shipped output, not slideware.
Integrate
Your tools, your rituals, your repositories: the team adopts your workflow, not the reverse.
Scale
Add roles as velocity proves out; our bench lets teams grow without months of recruiting.
Review & renew
Quarterly reviews on velocity, quality and cost, so the engagement earns its renewal.
Frequently asked questions.
Why use Java and Spring for a new backend in the first place?
Maturity and staying power. Java offers a battle-tested runtime, a vast library ecosystem and a hiring market in every country; Spring Boot adds convention-driven productivity, first-class security and a clean path to microservices. For systems expected to live a decade, that combination minimizes both technical and organizational risk.
Can your Java team work inside our existing codebase and standards?
Yes. Most engagements start inside an existing estate. We onboard against your coding standards, branching model and CI/CD, and where standards are missing we propose them explicitly rather than importing habits silently.
How do you keep offshore Java delivery predictable?
Named squads with CVs you approve, two-week sprints with demos, transparent velocity metrics and a delivery lead accountable for communication. Beirut’s time zone overlaps the full European working day, so collaboration is same-day, not next-day.
Who owns the code and IP?
You do, unambiguously. Code lives in your repositories from day one, contracts assign all IP to you, and documentation is a deliverable: the same terms as every Eurisko offshore engagement.
Can you modernize a legacy Java application?
Yes. We upgrade old Java and Spring versions step by step, move monoliths toward modular services where it pays off, and keep the system running in production throughout. Each step ships behind tests, so the business never waits for a big-bang rewrite.
Which databases and messaging tools do your Java teams use?
PostgreSQL, Oracle, MySQL and MongoDB for data, Kafka and RabbitMQ for messaging, and Redis for caching, chosen per workload. Where you already run a stack, we work with it rather than replacing it.
