Hire Offshore Java Developers
DeltaCubes provides offshore Java developers who build Spring Boot microservices, enterprise integrations and data-heavy back ends as part of your team. Clients use them to add backend capacity, rewrite ageing Java platforms and scale services on AWS or Azure, with contracts and account management run from our US office in Princeton, New Jersey.
What our Java developers build
Java is still the default choice for systems that have to be reliable, auditable and fast under load, which is why it runs so much of healthcare, finance and enterprise software. Our Java developers work across that range, from a single service to a full platform.
- Spring Boot microservices and REST APIs
- Event-driven systems with Kafka or RabbitMQ
- Enterprise integrations: ERP, CRM, payment gateways and HL7/FHIR healthcare data
- Data-heavy back ends on SQL Server, PostgreSQL, MySQL and Oracle
- Rewrites of monolithic Java applications into maintainable services
Rewriting and scaling Java platforms
A common reason clients come to us is a Java system that has outgrown its original design: slow releases, fragile deployments and data spread across too many databases. Our Java developers break the work into stages, put tests around the existing behaviour, then rebuild or split out services so the platform can grow without each release becoming a risk.
For example, DeltaCubes rewrote a Java-based patient data platform serving 150+ healthcare centers, consolidating data from 150 databases into one scalable warehouse.
Working with your US team
Our Java developers join your stand-ups, work in your repositories and issue tracker, and keep a planned overlap with US Eastern and Central hours. You interview every developer before they start, and contracts and billing run through DeltaCubes Technology LLC in the US.

FAQs: hiring offshore Java developers
Do your Java developers work with Spring Boot and microservices?
Yes. Spring Boot is the main framework our Java developers use, for both new microservices and REST APIs on existing platforms. They also work with Spring Cloud, Kafka or RabbitMQ for messaging, and deploy with Docker and Kubernetes on AWS or Azure.
Can you rewrite or modernise a legacy Java application?
Yes. We modernise legacy Java systems in stages: adding tests around current behaviour, upgrading the Java and framework versions, and splitting out services where it helps. DeltaCubes has rewritten a Java patient data platform serving 150+ healthcare centers this way.
Can I interview the Java developer before they start?
Yes. We share profiles matched to your stack and seniority needs, and you interview the shortlisted developers yourself. Nobody joins your team until you approve them, and a replacement developer is available if the fit is not right.
Do your Java developers have healthcare or finance experience?
Yes. DeltaCubes Java developers have delivered healthcare data platforms and supported fintech systems running on Java microservices. When you share your requirements, we look for developers with experience in your industry and its compliance needs.
How much does it cost to hire an offshore Java developer?
Rates depend on the Java skills, seniority and engagement model you need. They are negotiable and are confirmed in the official proposal and agreement DeltaCubes shares once we understand your requirements. Contact us with the roles you need and we will send a proposal.
