Hire Java Developers

Our Java developers build on:

• Spring Boot, the default for most enterprise REST APIs and service layers we build.
• Quarkus, our cloud-native, Kubernetes-native pick for teams optimizing for fast startup and low memory footprint in containerized environments. Quarkus is often the better fit for greenfield microservices, and our engineers use it in production.
• Micronaut, for compile-time dependency injection and AOT-friendly services where boot time and footprint matter as much as they do with Quarkus.
• Microservices architecture, with Kafka or RabbitMQ for event-driven and asynchronous messaging between services.
• Docker and Kubernetes for containerization and orchestration, so what we build is deployable the way your platform team already runs things.

Building a Java backend that needs a matching frontend or a Node.js service layer? Our Node.js developers and React developers work inside the same delivery process, or see our full-stack developers if you’d rather hire one team that spans both ends.

Modernize Spring applications by moving from older Spring Boot versions to current releases, including the javax to jakarta namespace transition where required. Devox Software assesses dependencies, updates configuration, resolves compatibility issues, modernizes security and persistence layers, refreshes tests, and validates production behavior after the upgrade.

The goal is to reduce maintenance risk, move away from aging dependencies, and give the application a more current foundation for future development.

Modernize legacy enterprise Java applications by moving away from heavyweight application servers toward Spring Boot, containerized services, or cloud-native deployment models where the architecture justifies it. The work includes dependency analysis, service extraction, API redesign, persistence migration, deployment changes, and phased replacement of legacy components.

The objective is to improve maintainability, deployment flexibility, and operational control without forcing a disruptive full rewrite.

Improve throughput and resource efficiency by reviewing concurrency models, thread usage, heap behavior, garbage collection, memory pressure, and application-level bottlenecks. For workloads that fit the model, Java virtual threads can simplify high-concurrency designs while reducing the need for more complex asynchronous code.

The focus is on measurable performance improvement based on profiling and workload behavior rather than tuning JVM settings in isolation.

Use GraalVM native image compilation where faster startup, lower memory usage, or smaller runtime footprints create meaningful operational value. Devox Software’s team assesses framework compatibility, reflection and serialization requirements, build configuration, test coverage, and deployment implications before introducing native compilation.

This approach can be useful for selected microservices, serverless workloads, and containerized applications where startup time and resource efficiency matter.

Add AI capabilities to Java applications using tools such as Spring AI, LangChain4j, model APIs, retrieval pipelines, vector databases, and existing enterprise data sources. Devox Software’s team supports chat and copilot experiences, RAG, semantic search, document processing, workflow automation, and AI-enabled backend services.

Our focus is on integrating AI into existing Java architecture with clear controls around permissions, observability, cost, data access, and human review where needed.

Design and build event-driven Java systems using Apache Kafka and related messaging patterns for asynchronous workflows, integration, and high-volume data movement. The service can cover event design, producers and consumers, schema management, retries, idempotency, stream processing, observability, and failure handling.

The goal is to improve decoupling and scalability without turning event-driven architecture into unnecessary complexity.

Build or modernize JVM applications with Kotlin where its language features, interoperability with Java, and developer ergonomics fit the product and team. Our specialists support Kotlin-based Spring services, mixed Java/Kotlin codebases, gradual migration, testing, and backend development.

This can be especially useful when teams want to modernize the development experience while preserving access to the wider JVM ecosystem.

Improve visibility into Java applications through distributed tracing, metrics, logs, and service-level telemetry using OpenTelemetry-compatible instrumentation. Devox Software’s team helps instrument services, propagate trace context, define meaningful telemetry, and integrate observability data with existing monitoring platforms.

Our goal is to make production behavior easier to understand so teams can diagnose latency, failures, dependency issues, and service interactions with better context.

We excel at supporting enterprises in accelerating their business processes. Hire Java developers from Devox Software to build CRMs, BI, accounting systems, and other solutions you need.

Java 8 to Java 21 LTS is the migration we’re asked for most often, usually from teams whose Java 8 or 11 systems have quietly become the thing nobody wants to touch. Our approach:

• Dependency and codebase audit. We map every library, framework version, and deprecated API your current system depends on before writing a migration plan, so you know the real scope before we start.
• Phased migration without downtime. We move services incrementally rather than in one cutover, keeping the production system live and rollback-able at every stage.
• Post-upgrade test coverage. Every migrated module ships with test coverage validating that behavior didn’t silently change along with the runtime, not just that it compiles.

The end state is a system on Java 21 LTS with current security support, without a multi-month freeze on shipping anything else.
