Enterprise Java applications, Spring Boot microservices, and payment systems built by senior engineers who've shipped for companies like Pine Labs and KredX.
Trusted by engineering teams at
Large-scale Java applications built on Spring Boot 3, designed for complex business logic and long-term maintainability. Java domain-driven design, strict layering, and comprehensive test coverage. Systems that handle millions of transactions and stay stable under regulatory scrutiny.
High-throughput REST and gRPC APIs using Spring Boot 3 and Spring Cloud. Service discovery, circuit breakers, distributed tracing, and centralized configuration. We design service boundaries around business domains, not technical convenience.
Migrate from Java 8/11, Struts, or EJB-based systems to modern Java 21 with Spring Boot 3. Incremental strategies using strangler fig patterns so your system stays live during the transition. No big-bang rewrites.
Java applications optimized for containers and serverless. GraalVM native images for sub-second startup times and 50-70% lower memory footprint. Quarkus for Kubernetes-native Java when Spring Boot's footprint is too heavy for your infrastructure budget.
Transaction processing, payment gateway integrations, and financial reconciliation systems. PCI-DSS compliant architecture with audit logging, idempotency, and fault tolerance. Built with the same rigor we bring to [fintech clients](/industries/financial-services) like Pine Labs.
Robust API backends for iOS and Android applications. Spring Boot APIs with proper versioning, push notification services, OAuth 2.1 authentication, and WebSocket support for real-time features. Designed to serve [mobile frontends](/services/mobile-development) at scale.
Java 21 records, sealed classes, pattern matching, and virtual threads are not optional extras. We use modern Java features to write cleaner, more maintainable code. If your codebase still looks like Java 8, something is wrong.
Not every system needs 50 microservices. Not every application belongs in a monolith. We size services based on team boundaries, deployment frequency, and scaling requirements. Architecture follows organizational reality, not conference talks.
JUnit 5 and Testcontainers are part of every project from day one. We write tests that verify business behavior, not implementation details. Test coverage exists to give teams confidence to change code, not to hit a number.
Structured logging with SLF4J, distributed tracing with OpenTelemetry, and health checks are baked into the initial scaffold. When something breaks in production, the first question should be 'what happened,' not 'how do we find out.'
Every Java system we build can be maintained by your team independently. Clean architecture, documented decisions, and zero proprietary dependencies. We build for your future, not our recurring revenue.
Map your system requirements, integration points, and scalability targets. Choose between Spring Boot, Quarkus, or a hybrid approach based on actual workload characteristics. Deliverable: architecture decision records, service diagrams, and a technical proposal.
API contracts documented in OpenAPI before code is written. Database schema designed with Hibernate mappings, migration scripts in Flyway, and proper indexing strategy. Your frontend team can build against mocked endpoints immediately.
Sprint-based Java development with working services shipped every two weeks. JUnit 5 and Testcontainers for reliable automated testing. Staging environments from week one. You review real code, not slide decks.
Simulate production traffic patterns using Gatling or k6. Connection pool tuning, query optimization, JVM profiling with async-profiler, and caching layer validation. Nothing ships until it handles your expected load with headroom.
Architecture decision records, Javadoc-generated API documentation, runbooks, and deployment guides. Your team owns the system entirely. Optional support retainer available, but no lock-in.
Engineers with 5+ years building production Java systems in Spring Boot, Hibernate, and cloud-native environments. Full backend capability spanning API design, database optimization, and infrastructure.
A self-contained team that owns full service delivery. Architecture, implementation, testing, and deployment covered. The lead handles technical decisions and stakeholder communication.
Fixed-scope engagement with clear deliverables, timeline, and budget. Defined service contracts, agreed milestones, and transparent pricing.
Talk directly with engineers, not sales. We will assess fit and give honest next steps.

Java development services typically range based on project complexity. API backends with 10-20 endpoints run $20,000 to $50,000. Microservices platforms with 5-10 services sit in the $60,000 to $200,000 range. Full enterprise applications with complex integrations, compliance requirements, and transaction processing can run $150,000 to $500,000+. Dedicated Java developer hiring starts at $4,000/month.
