Learn MoreWhat We Build For You with Java
Java has powered enterprise software for nearly 30 years — and it is stronger than ever. Strongly typed, garbage collected, platform independent, and backed by the largest developer community on the planet. From banking backends processing billions of dollars to Android apps used by billions of people, Java is the language businesses trust when failure is not an option. Here is what we build with it.
Enterprise Web Applications
We build enterprise-grade web applications with Spring Boot and Spring MVC — the gold standard for Java backend development. Admin dashboards, SaaS platforms, ERP systems, CRM portals, and multi-tenant applications with role-based access control, SSO authentication (SAML, OAuth 2.0, LDAP), audit logging, and compliance features. Spring Security handles authentication and authorization out of the box. We use Thymeleaf or integrate with React/Angular frontends, connect to PostgreSQL, MySQL, or Oracle with JPA/Hibernate, and deploy on Tomcat, Jetty, or embedded servers. Your application is secure, testable with JUnit and Mockito, and built to handle thousands of concurrent users.
Microservices & Spring Cloud
We architect Java microservices that are independently deployable, horizontally scalable, and fault-tolerant. Spring Boot for each service, Spring Cloud for service discovery (Eureka), configuration management (Config Server), circuit breakers (Resilience4j), API gateway (Spring Cloud Gateway), and distributed tracing (Zipkin, Sleuth). Each microservice runs in a Docker container, communicates via REST, gRPC, or message queues (RabbitMQ, Apache Kafka), and deploys to Kubernetes. We implement saga patterns for distributed transactions, event sourcing with Axon Framework, and CQRS for read/write separation. Your system scales each service independently — no single point of failure.
REST APIs & Backend Systems
We build high-performance REST APIs and GraphQL backends with Spring Boot that handle millions of requests daily. Proper request validation with Bean Validation (JSR 380), exception handling, HATEOAS, pagination, filtering, and API versioning. We implement JWT and OAuth 2.0 authentication with Spring Security, rate limiting, caching with Redis or Ehcache, and comprehensive API documentation with Swagger/OpenAPI. Your API connects to any database using Spring Data JPA, Hibernate, or MyBatis — with connection pooling (HikariCP), query optimization, and transaction management. Fully tested with JUnit 5, Mockito, and integration tests using Testcontainers. Production-ready from day one.
Android App Development
Java is the original language of Android — and still powers millions of apps on the Google Play Store. We build native Android applications with clean MVVM/MVP architecture, Retrofit for API calls, Room for local database, LiveData and ViewModel for reactive UI, Dagger/Hilt for dependency injection, and Material Design for beautiful interfaces. E-commerce apps, fintech apps, healthcare apps, logistics trackers, social platforms — we build them all. We also maintain and modernize existing Java Android codebases, add new features, fix performance issues, and ensure compatibility across all Android versions and screen sizes. Your app is tested, optimized, and ready for the Play Store.
Big Data & Real-Time Processing
Java dominates big data. We build data processing systems with Apache Kafka for real-time event streaming, Apache Spark for batch and stream processing, Apache Flink for complex event processing, and Elasticsearch for full-text search and analytics. We design event-driven architectures that process millions of events per second — transaction monitoring for banks, real-time recommendation engines, IoT sensor data pipelines, and log analytics platforms. We integrate with Hadoop, Cassandra, HBase, and cloud data services (AWS Kinesis, GCP Pub/Sub). Your data flows in real time, gets processed instantly, and powers the dashboards and alerts your business depends on.
Legacy Modernization & Migration
Still running Java 8 or older? Stuck on monolithic J2EE, Struts, or JSP? We modernize your Java stack. We migrate legacy applications to Spring Boot, upgrade from Java 8/11 to Java 21 with modern features (records, sealed classes, virtual threads, pattern matching), refactor monoliths into microservices, replace EJBs with lightweight Spring components, and move from on-premise servers to cloud (AWS, Azure, GCP). We do it incrementally — module by module — so your system never goes down during the transition. We also improve build pipelines (Maven to Gradle), add proper testing, implement CI/CD, and containerize with Docker. Your legacy Java app becomes a modern, maintainable, high-performance system.

Frequently Asked Questions
Got questions about Java? Here are simple, honest answers to what people ask us most.
Why should I choose Java for my project?
Java is the most reliable, battle-tested programming language for enterprise software. It runs on 3+ billion devices, powers 90% of Fortune 500 backends, and has nearly 30 years of proven stability. Java gives you strong typing (bugs caught at compile time, not in production), platform independence ("write once, run anywhere" on the JVM), world-class performance (JIT compilation, garbage collection), and the largest ecosystem of enterprise libraries and frameworks. Google, Amazon, Netflix, LinkedIn, Uber, and every major bank in the world run on Java. If you need software that is secure, scalable, and built to last — Java is the answer.
Java vs Python vs Node.js — which one should I pick?
Each excels in different areas. Python dominates AI/ML and data science. Node.js is great for real-time apps and lightweight APIs. Java wins for enterprise-grade systems that need rock-solid reliability, strict type safety, and massive scalability. Java's JVM is one of the most optimized runtimes ever built — it handles high-concurrency, CPU-intensive workloads better than Python or Node.js. If you are building banking software, healthcare platforms, e-commerce backends, ERP systems, or anything where downtime costs money — Java is typically the best choice. We help you evaluate your specific needs and choose the right technology.
Is Java still relevant in 2026?
More relevant than ever. Java consistently ranks in the top 3 programming languages worldwide (TIOBE, Stack Overflow). Modern Java (21+) is nothing like the verbose Java of 10 years ago — it now has records, sealed classes, pattern matching, virtual threads (Project Loom), and a 6-month release cycle that keeps it cutting edge. Spring Boot 3 with GraalVM native images starts in milliseconds and uses minimal memory. Netflix processes billions of API calls daily with Java. Amazon built most of AWS on Java. LinkedIn, Uber, and Airbnb all rely on Java microservices. Java is not just relevant — it is thriving.
Do you use Spring Boot for all Java projects?
Spring Boot is our default choice for most Java backend projects because it eliminates boilerplate, provides production-ready defaults, and integrates with everything — databases, message queues, security, caching, cloud services. But we also use Quarkus and Micronaut for cloud-native microservices that need ultra-fast startup times and low memory footprint (ideal for serverless/Kubernetes). For Android, we use the Android SDK with Kotlin/Java. For big data, we use Apache frameworks (Kafka, Spark, Flink). We choose the right Java framework for your specific requirements — not a one-size-fits-all approach.
How long does it take to build a Java application?
It depends on complexity. A REST API with authentication and CRUD takes 3-5 weeks. A medium-complexity enterprise web app with Spring Boot takes 8-14 weeks. A full microservices platform or enterprise system can take 4-8 months. Java projects may take slightly longer to set up than Python or Node.js, but the payoff is massive — stronger type safety means fewer production bugs, and the architecture scales without rewriting. We work in 2-week agile sprints, ship working features incrementally, and give you a detailed timeline and cost breakdown before development begins.
Do you provide ongoing Java support and maintenance?
Yes. After launch, we handle everything — bug fixes, performance tuning, Java version upgrades (LTS releases), Spring Boot upgrades, security patches, dependency updates, and new feature development. We set up CI/CD with Jenkins, GitHub Actions, or GitLab CI, write comprehensive tests with JUnit 5 and Mockito, monitor with Prometheus, Grafana, and ELK Stack, and manage cloud infrastructure on AWS, Azure, or GCP. We audit your Maven/Gradle dependencies for vulnerabilities using OWASP Dependency-Check and Snyk, optimize JVM garbage collection and heap settings, and profile with VisualVM or JFR. Think of us as your Java engineering team — we keep your systems fast, secure, and running 24/7.
