Enterprise-grade Java development services
Build secure, scalable, and high-performance backend solutions. From architectural strategy to seamless execution, our senior engineering teams deliver Java software that drives long-term business stability and growth.
Modern Java Engineering That Delivers Business Value
Java remains the foundation of enterprise software, but modern development demands more than legacy maintenance. Our senior engineering teams transform Java into a competitive advantage whether you're modernizing monolithic systems, building cloud-native microservices, or scaling existing infrastructure.
With deep expertise in Spring Boot, Hibernate, and cloud-native architectures, we deliver Java solutions that reduce operational costs, accelerate time-to-market, and adapt as your business grows.
Systems engineered to handle high concurrency, complex business logic, and massive data volumes while maintaining sub-second response times.
OWASP-compliant development, OAuth2/JWT implementation, and comprehensive security audits that protect your data and meet compliance requirements.
Deep integration with AWS, Azure, and GCP. We build containerized microservices with Kubernetes orchestration for seamless scalability.
Agile methodologies with 2-week sprints, transparent progress tracking, and realistic estimates based on our 15+ years of Java experience.
Automated testing pipelines, CI/CD with Jenkins/GitLab, and zero-downtime deployments that keep your systems running 24/7.
Strategic refactoring, modernization roadmaps, and code quality improvements that reduce maintenance costs by up to 40%.

Common questions about Java development with Cleverix
Here's what CTOs, engineering directors, and product teams typically ask before partnering with us for enterprise Java development.
We work on enterprise applications, microservices architectures, legacy system modernization, API platforms, and custom backend systems. Most clients engage us for Spring Boot/Cloud projects, Java 17/21 migrations, or building cloud-native solutions on AWS/Azure.
Yes. We specialize in incremental modernization—assessing your system, identifying refactoring opportunities, migrating to current Java LTS versions, and extracting services without disrupting production. We've migrated 40+ legacy Java systems to modern architectures.
After architecture discovery and team alignment, senior Java engineers typically start within 2-4 weeks. Timeline depends on team size requirements and specific expertise needed (e.g., Spring Cloud, Kafka, specific cloud platforms).
Absolutely. Our Java teams join your Jira/GitHub workflows, participate in standups and code reviews, and follow your development standards. They work as embedded team members, not external contractors—taking ownership of features, technical decisions, and production issues.
Most engagements use a monthly rate per engineer or dedicated squad model. For defined scopes (like migrations or specific features), we can provide fixed-price estimates. All models include transparent reporting, and you control team scaling month-to-month.
All work is covered by NDAs and IP assignment agreements. Engineers follow your security protocols, use your VPN/access controls, and we support SOC 2 and ISO compliance requirements. Your code and infrastructure remain fully under your control.
Teams are flexible. You can scale up when roadmap demands increase or scale down after major releases. We typically ask for 30 days notice for changes, but can accommodate faster adjustments when needed. No long-term lock-in contracts.
