Java Development Services
CrestCoder builds high-performance Node.js backends and APIs for businesses across India, Australia, South Africa, and the UK. Java 25 LTS backends with Spring Boot, flexible constructors, scoped values, and compact source files — modern Java that has moved far beyond the boilerplate reputation.
Java 25 LTS (Sept 2025) ships 18 JEPs: flexible constructors, compact source files, scoped values, AOT profiling, and compact object headers. The boilerplate-heavy Java of 2010 is gone.
Java 25 lets you write statements before super() — proper validation and setup in constructors without awkward workarounds.
No more public-static-void-main ceremony for simple programs. Module imports replace verbose import lists. Java is finally approachable for quick scripts too.
Virtual threads (finalized in Java 21, improved since) make high-concurrency I/O straightforward without reactive programming complexity.
AOT method profiling and compact object headers in Java 25 improve startup time and memory footprint — important for cloud-native and containerised deployments.
REST APIs and web applications on Spring Boot with Spring Security, JPA/Hibernate, and production-grade configuration.
Multi-tenant enterprise systems, admin portals, and internal tools with role-based access and audit logging.
Service-based architectures with Kafka, RabbitMQ, or SQS — when splitting a monolith genuinely helps, not just for the resume.
Java applications containerised with Docker and deployed to AWS, Azure, or on-prem Kubernetes.
JPA/Hibernate for relational databases, with proper migration management and query optimisation.
Java LTS version upgrades (21→25), dependency audits, and ongoing feature development under a monthly retainer.
Our catalog does not include a dedicated Java case study — we are transparent about that. What we bring to Java projects is the same enterprise-grade discipline we apply across our backend work: clean layering, proper dependency injection, and codebases that scale with the team.
We follow Spring Boot best practices: layered architecture, proper use of Spring Security and JPA, database migration management, and API documentation via OpenAPI. The patterns are the same whether the codebase is greenfield or a modernisation from older Java versions.
We build on Java 25 LTS (supported 5+ years by most vendors) and plan version upgrades as a scheduled engineering activity.
Java's type system has always been strong, and Java 25's pattern matching, records, and sealed classes make it expressive too.
Two-week sprints with a working demo at the end of each — you see real software, not slide decks.
Small enough that senior engineers stay hands-on, large enough to staff a dedicated team when you need one.
We map out API design, data model, and deployment strategy before writing code.
API contracts and JPA entities designed early so your frontend team can build in parallel.
Two-week sprints with a working demo at the end of each, deployed to a staging environment you can access anytime.
Unit tests with JUnit, integration tests with Testcontainers, and CI/CD pipeline setup before launch.
Production deployment, then an optional monthly retainer for Java upgrades and continued feature work.
We reply within 24 hours with an honest architecture recommendation — no obligation.
