Startups
We help startups build scalable Java backends from the ground up. From API design to cloud deployment, our engineers build systems that grow with your user base without requiring a full rebuild every 18 months.
Backend scaling bottlenecks slowing your platform as user numbers grow?
Struggling to find senior Java engineers who understand your system complexity?
Hire Java Developers
Senior Java engineers who build backend systems that handle real load -- enterprise APIs, microservices, data pipelines, and system integrations -- delivered with full source code ownership.
Java backend engineers with enterprise, fintech, and platform experience
Flexible models -- part-time, full-time, or dedicated team
Start in days, not weeks. Fixed cost or retainer.
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, scalable, and built to handle the data volumes and transaction loads 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.
Hire Java developers who've built systems at scale
Senior engineers, flexible models, full source code ownership.
What Sets Our Java Developers Apart
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
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.
Cost-Effective
Senior Java talent at a fraction of local hiring cost. No recruitment overhead, no benefits administration, no notice period. You pay for engineering output.
Regular Reporting
Daily standups, weekly progress summaries, sprint reviews -- at the cadence you need. You always know what's been built, what's in progress, and what's next.
Clear Communication
English-proficient engineers working in your timezone (or with significant overlap). Slack, Asana, Jira -- whatever tools your team already uses.
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 the 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.
