In short
RaftLabs provides Java developers who have shipped production enterprise APIs, microservices architectures, and data pipelines for clients in the US, UK, and Australia. Engagements run part-time, full-time, or as a dedicated team. Developers start within 1-2 weeks at USD 2,400/month.
Java developers who have shipped production backends
Hiring Java developers sounds straightforward. Finding ones who can design systems that hold up under real enterprise load is a different problem.
We've worked with Java across enterprise, fintech, and platform businesses. In that time, we've built API gateways handling millions of daily transactions, Spring Boot microservices architectures, and multi-tenant SaaS backends still running for clients in the US, UK, Ireland, and Australia. These aren't portfolio pieces, they're live systems with paying users and SLAs to meet.
If you need engineers who have debugged concurrency issues, tuned JVM under load, and decomposed a monolith into independently deployable services, that's the work we do.
Who We Work With
We work with teams that need senior Java engineers, not just developers who can write syntax.
Enterprises
For enterprises, we augment engineering teams with experienced Java developers who understand distributed systems, security compliance, and legacy system integration, delivering without disrupting your existing operations.
Scale-Ups
Scale-ups need backend engineers who can move fast without creating technical debt. We bring Java engineers who have shipped production systems at scale and know which shortcuts to avoid.
Agencies & Tech Partners
We act as your backend Java resource for client projects, embedded in your delivery process, following your standards, and moving at your pace. White-label or branded, your choice.
Our Java Development Services
Enterprise Java Development
Full-stack enterprise Java applications built with Spring Boot, Hibernate, and cloud-native architectures. Secure, built to handle the data volumes and transaction loads that enterprise systems require.
Microservices Architecture
Design and implementation of Java microservices using Spring Cloud and Docker/Kubernetes. We break monoliths into maintainable services and build new systems as composable, independently deployable units from day one.
API Development and Integration
RESTful and GraphQL APIs built in Java, designed for performance, documented, and secured. We also handle third-party API integrations, connecting your Java backend to payment gateways, ERP systems, and data providers.
Backend for Mobile and Web
Java backends that power your mobile and web frontends. Authentication, authorisation, data management, push notifications, and real-time features, built to serve your product across all client platforms.
Legacy Java Modernisation
We upgrade legacy Java systems to modern frameworks, improve performance, and refactor codebases to reduce technical debt. Phased migrations that keep production running while the system improves beneath it.
Java Performance Optimisation
Profiling, query optimisation, JVM tuning, and architectural refactoring to improve throughput and reduce latency. We diagnose bottlenecks in existing Java systems and fix the root causes, not just the symptoms.
Why hire Java developers from us?
Production Java Experience
Our Java engineers have built systems handling millions of transactions. They understand concurrency, memory management, and distributed systems, not just framework documentation.
Flexible Engagement Models
Part-time for specific modules, full-time for sustained delivery, or a dedicated team for a full product build. We match the engagement model to your actual project phase.
Transparent Pricing
Senior Java talent at a fraction of local hiring cost. Fixed monthly rates with no hidden costs. You know exactly what you're paying for before we start. Rates from USD 2,400/month for part-time engagement.
Regular Reporting
Daily standups, weekly progress summaries, sprint reviews, at the cadence you need. We track work in Asana and communicate on Slack. You always know what's been built, what's in progress, and what's next.
Proactive Problem-Solving
We flag issues before they slow your project down. Our engineers have shipped enough Java backends to know where the common failure points are, and how to avoid them.
Security-First Development
Input validation, secure API design, dependency audits, and OWASP compliance built into the development process, not added as an afterthought before go-live.

Frequently Asked Questions
Our Java developers primarily work with Spring Boot and Spring Cloud for modern microservices and REST APIs, Hibernate/JPA for ORM, and Maven/Gradle for build management. For legacy system work, we're comfortable with older Spring versions, Java EE, and custom frameworks. The stack is determined by your project requirements, not a fixed template.
Yes. Most Java engagements start with a codebase review to understand the existing architecture, identify technical debt, and establish coding standards. We integrate with your existing CI/CD pipelines, version control, and deployment infrastructure. Our engineers adapt to your patterns rather than imposing a new approach without context.
Security practices are built into the development process, input validation, secure API design, authentication and authorisation architecture, SQL injection prevention, and dependency vulnerability scanning. For regulated industries (fintech, healthcare), we design systems around specific compliance requirements (PCI DSS, HIPAA, GDPR) from the architecture stage rather than retrofitting controls later.
Our part-time retainer starts at one month (10 work days). For project-based engagements, the minimum project scope is typically 6–8 weeks for an MVP backend. We don't impose long-term lock-ins, most clients extend engagements because the work is going well, not because they're contractually obligated to.
Part-time from USD 2,400/month (80 hours). Full-time from USD 4,800/month (160 hours). Dedicated teams from USD 15,000/month. Project work from USD 10,000 for MVP scope.
Contact us for a tailored quote based on your specific requirements.
Most engagements start within 1-2 weeks of signing. We have developers available on short notice for urgent projects. The discovery call and proposal typically happen within 2-3 business days of your initial contact.
Yes. We sign NDAs as standard practice for all client engagements. Contact us to get the process started.
We use Slack for day-to-day communication and Asana for project tracking. You will have direct access to your developer and a dedicated project coordinator throughout the engagement. Daily standups or weekly syncs are available depending on your preference.
Yes. Java has been the backbone of enterprise software for decades. Its strong typing, mature ecosystem (Spring Boot, Kafka, Hibernate), JVM performance tuning capabilities, and extensive support for concurrency make it well-suited for high-transaction, compliance-heavy, and long-lived systems. Banks, logistics platforms, and large SaaS companies rely on Java for critical backend infrastructure precisely because of its stability and ecosystem depth.
A freelancer gives you one person. An agency gives you a team with process, backup coverage, and accountability. With RaftLabs, your Java developer works within a structured team that includes a project coordinator, senior peer review, and QA. If a developer is unavailable, the project doesn't stop. With a freelancer, it often does.
