What It Is

The technology that powers your product

We don’t just use technology — we master it. Every stack we work with is chosen for its performance, scalability, and developer experience. Then we push it further.

Core Benefits

Why Choose Java & Spring Boot for Your Enterprise Application?

01

Proven Enterprise Reliability

The JVM has powered the world's largest financial, e-commerce, and logistics systems for over two decades. Spring Boot's production-ready Actuator endpoints, health checks, and metrics integration make it straightforward to build services that meet enterprise SLA requirements of 99.9% uptime and beyond.

02

Rich Microservices Ecosystem

Spring Cloud provides service discovery with Eureka, distributed configuration with Config Server, circuit breaking with Resilience4j, and distributed tracing with Micrometer — giving teams a complete microservices toolkit without vendor lock-in or custom infrastructure engineering.

03

Reactive & High-Throughput Processing

Spring WebFlux and Project Reactor enable non-blocking, reactive APIs that handle thousands of concurrent connections on minimal hardware. For event-driven architectures, Spring Kafka and Spring AMQP deliver reliable, exactly-once message processing at scale.

04

Cloud-Native & Container-First

Spring Boot's layered JAR support, GraalVM native image compilation, and Buildpacks integration produce lean container images optimized for Kubernetes. Startup times measured in milliseconds and reduced memory footprints make Java viable even in serverless and scale-to-zero deployment models.

Capabilities

Our Java & Spring Boot Development Capabilities

01
Capability

Microservices Architecture & Domain-Driven Design

Zetaton decomposes complex domains into independently deployable Spring Boot services bounded by clear domain contexts. We design event-driven communication via Kafka or RabbitMQ, implement saga patterns for distributed transactions, and use Spring Cloud Gateway as the API entry point with rate limiting and authentication filters.

02
Capability

REST & gRPC API Engineering

Our engineers build versioned RESTful APIs following OpenAPI 3 specifications and high-performance gRPC services for inter-service communication. We implement pagination, HATEOAS hypermedia, and idempotency keys so APIs are developer-friendly, spec-compliant, and safe to consume from web and mobile clients alike.

03
Capability

Data Layer & Persistence Design

Zetaton architects Spring Data JPA repositories with Hibernate optimizations, query-specific Criteria API or JPQL for complex reporting, and Spring Data MongoDB or Redis for polyglot persistence requirements. Database migrations with Flyway and connection pool tuning with HikariCP ensure consistent schema evolution and predictable query performance.

04
Capability

Security, OAuth2 & Compliance Engineering

Spring Security powers our authorization servers, resource server configurations, and method-level security annotations. We implement OAuth 2.0 and OIDC flows with Keycloak or Okta, enforce row-level security for multi-tenant SaaS products, and configure audit logging to satisfy SOC 2 and PCI-DSS compliance requirements.

Our Portfolio

Java & Spring Boot Projects

Zetaton's Java delivery process combines Domain-Driven Design workshops, test-driven development, and continuous integration to produce Spring Boot services that are observable, resilient, and ready for enterprise production from the first release.

PRJ 01

Ciye Mobile App

Built mobile social commerce application on Java and Spring Boot, delivering enterprise-grade reliability with microservice architecture.

PRJ 02

Unico Well Monitoring

Built industrial well monitoring and analytics platform on Java and Spring Boot, delivering enterprise-grade reliability with microservice architecture.

How We Build It

Our proven process

A structured approach that delivers on time, every time.

1

Domain Analysis & Bounded Context Mapping

We run Event Storming workshops with your product and engineering stakeholders to identify aggregates, domain events, and service boundaries. The resulting context map becomes the authoritative blueprint for microservice decomposition and API contract design throughout the engagement.

2

Spring Boot Project Scaffolding & Standards

Zetaton generates production-ready Spring Boot projects with pre-configured logging, Actuator health endpoints, Micrometer metrics, OpenAPI documentation, and Docker Compose local development stacks. Coding standards, Checkstyle rules, and branch protection policies are established before feature development begins.

3

Test-Driven Feature Development

Features are developed using TDD with JUnit 5, Mockito, AssertJ, and Testcontainers for integration tests against real database and message broker instances. Mutation testing with PIT validates that tests catch genuine defects, not just inflate coverage numbers on the CI dashboard.

4

Performance & Resilience Engineering

We inject Resilience4j circuit breakers, bulkheads, and retry policies at service boundaries. Gatling load tests validate throughput and latency under peak concurrency, JFR flight recordings identify GC pressure and thread contention, and heap analysis confirms memory efficiency before every major release.

5

Container Build & Kubernetes Deployment

Spring Boot applications are containerized with Jib or Buildpacks for reproducible, minimal Docker images. We author Kubernetes manifests or Helm charts with liveness and readiness probes, horizontal pod autoscalers, and resource quotas configured to match production traffic profiles and cost targets.

6

Observability, Alerting & Handover

Structured JSON logging, Micrometer-to-Prometheus metrics, and OpenTelemetry distributed traces are wired to Grafana dashboards. Alert rules covering error rates, p99 latency, and JVM heap saturation are configured so your operations team has full visibility the moment the application goes live.

The Zetaton Edge

Why Choose Zetaton for Java & Spring Boot Development?

Deep Spring Ecosystem Mastery

Our team has production experience with Spring Boot, Spring Cloud, Spring Security, Spring Batch, and Spring Integration across banking, insurance, and high-growth SaaS environments. We understand Spring's internals deeply enough to diagnose subtle context refresh issues and performance anomalies that generic developers miss.

Cloud-Native & Kubernetes-Native Delivery

Zetaton delivers Spring Boot services packaged as lean OCI images, deployed to EKS, GKE, or AKS with GitOps pipelines via ArgoCD or Flux. Every service ships with Helm charts, runbooks, and Grafana dashboards so your platform team can operate it without Zetaton being in the critical path.

Monolith Modernization Expertise

We specialize in extracting microservices from legacy Spring MVC or EJB monoliths using the Strangler Fig pattern, implementing Anti-Corruption Layers to bridge old and new data models, and migrating database schemas incrementally without downtime to production systems.

Security-First Engineering

Security is embedded in our development lifecycle — OWASP dependency checks in CI, Spring Security configuration reviews, secrets management with HashiCorp Vault, and threat modeling sessions for sensitive data flows ensure your Java services meet enterprise security standards before they reach production.

Transparent Delivery & Knowledge Transfer

Architecture decision records, Confluence documentation, and live handover sessions ensure your engineering team fully understands the systems Zetaton builds. We measure success not only by delivery but by how quickly your team can confidently extend and operate the codebase independently.
