Java consultant

Java is one of the world's most widely used programming languages and is extensively used for enterprise applications, backend systems, financial platforms, cloud systems and Android development. The language's stability, scalability and large ecosystem make it a natural choice in large organisations.

• Enterprise applications: ERP, CRM and large business systems built on Java EE / Jakarta EE.
• Microservices: Spring Boot and Quarkus for scalable, cloud-native services.
• API development: RESTful and GraphQL APIs for modern application architecture.
• Fintech and banking: High-transaction systems with strong security and performance requirements.
• Big Data: Hadoop, Spark and Kafka-based data platforms.

A Java consultant can participate throughout the entire development lifecycle — from architecture design and coding to testing, deployment and performance optimisation.

• Architecture and design: Design of scalable and maintainable Java systems.
• Development: Implementation of features, services and integrations.
• Code review and quality: Review of existing codebase and technical debt.
• CI/CD and DevOps: Setting up pipelines with Maven, Gradle, Jenkins and GitHub Actions.
• Performance optimisation: JVM tuning, profiling and refactoring.

Java consultants are particularly valuable for complex integrations, modernisation of legacy systems and projects requiring high stability and scalability.

• Modernisation of monolithic Java systems to microservices
• New backend projects requiring enterprise-grade stability
• Short-term reinforcement of existing Java teams
• Performance analysis and optimisation of existing applications
