Spring Boot Without Configuration Chaos
Build REST APIs, microservices, and backends with auto-configuration that works and dependencies that don't conflict.
👋 Talk to a Spring Boot expert.
Trusted and top rated tech team
Java backends without XML or boilerplate
Spring Boot removes the configuration overhead that slows Java teams down. But misconfigured starters, dependency version conflicts, and production monitoring gaps still trip up projects. We build Spring Boot services with clean dependency trees, proper actuator setup, and configurations that work the same in dev and production.
Our capabilities include:
- REST API and microservices development
- Spring Cloud and distributed systems
- Spring Security and OAuth implementation
- Database integration with Spring Data
- Legacy Spring to Spring Boot migration
- Production monitoring and actuator configuration
Who we support
We work with Java teams building new microservices, migrating legacy Spring applications, or running Spring Boot in production without the operational visibility they need.
Teams Building Microservices
Your architecture calls for decomposed services but standing up each one takes longer than it should. Configuration sprawls across environments, dependencies conflict between services, and nobody has standardized how services communicate or handle failures.
Companies Modernizing Legacy Spring
Your XML-configured Spring apps still run but development has slowed to a crawl. New developers don't understand the configuration, upgrades feel risky, and you need a path to Spring Boot without rewriting everything at once.
Teams Needing Production Visibility
Your services deploy but you lack visibility into what's happening. Health checks are incomplete, metrics aren't flowing to your monitoring stack, and debugging production issues means digging through logs instead of dashboards.
Ways to engage
We offer a wide range of engagement models to meet our clients’ needs. From hourly consultation to fully managed solutions, our engagement models are designed to be flexible and customizable.
Staff Augmentation

Tools and technologies for Spring Boot development
Core Framework & Starters
Our engineers configure Spring Boot starters and auto-configuration to eliminate boilerplate while keeping dependency trees clean.
- Spring Boot — Opinionated framework with auto-configuration, embedded servers, and starter dependencies for rapid Java application development
- Spring Framework — Core dependency injection and aspect-oriented programming foundation that powers Spring Boot’s component model
- Spring Initializr — Project generator for bootstrapping Spring Boot applications with selected dependencies, build tools, and Java versions
- Starter Dependencies — Pre-configured dependency bundles like spring-boot-starter-web and spring-boot-starter-data-jpa that manage version compatibility
- Maven & Gradle — Build tools with Spring Boot plugins for packaging executable JARs, managing dependencies, and running applications
- DevTools — Development-time features including automatic restarts, live reload, and relaxed property defaults for faster iteration
Web & API Frameworks
Curotec builds REST APIs and reactive endpoints using Spring’s web frameworks with clean request handling and documentation.
- Spring MVC — Web framework for building REST controllers, request mapping, and response handling with annotation-driven configuration
- Spring WebFlux — Reactive web framework for non-blocking, asynchronous endpoints that handle high concurrency with fewer threads
- Spring HATEOAS — Library for building hypermedia-driven REST APIs with link generation and resource representation support
- Bean Validation — Request validation using annotations like @Valid, @NotNull, and custom validators for input sanitization
- Jackson — JSON serialization and deserialization with customizable mappers, date handling, and polymorphic type support
- OpenAPI & Springdoc — API documentation generation with Swagger UI integration for interactive endpoint testing and schema browsing
Data Access & Persistence
We implement database integration using Spring Data repositories, JPA mappings, and connection management tuned for load.
- Spring Data JPA — Repository abstraction for database access with query derivation, pagination, and auditing built on Hibernate ORM
- Hibernate — Object-relational mapping framework for entity management, lazy loading, caching, and schema generation from Java classes
- Spring Data JDBC — Lightweight data access without ORM complexity for teams preferring direct SQL control with Spring’s repository pattern
- HikariCP — High-performance connection pool included by default in Spring Boot for efficient database connection management
- Flyway & Liquibase — Database migration tools for version-controlled schema changes that run automatically on application startup
- Spring Data MongoDB — Repository support for MongoDB with document mapping, query builders, and reactive access for NoSQL workloads
Security & Authentication
Our team configures Spring Security with OAuth2, JWT validation, and access control that protects APIs without complexity.
- Spring Security — Framework for authentication, authorization, and protection against common vulnerabilities like CSRF and session fixation
- OAuth2 Resource Server — JWT validation and token-based authentication for securing APIs with external identity providers
- Spring Authorization Server — OAuth2 authorization server implementation for issuing tokens and managing client registrations
- Keycloak Integration — Open-source identity management with Spring Security adapters for SSO, user federation, and role mapping

FAQs about our Spring Boot services
How do you handle dependency version conflicts?
We manage BOMs and starter versions carefully, override dependencies only when necessary, and test compatibility across the full dependency tree. Conflicts get resolved before they cause runtime surprises.
Can you migrate our legacy Spring app to Spring Boot?
We migrate incrementally, converting XML configuration to annotations, updating dependency injection patterns, and replacing manual servlet setup with embedded servers. Production keeps running during the transition.
How do you structure microservices communication?
Depends on your requirements. Synchronous REST for simple calls, messaging with Kafka or RabbitMQ for event-driven flows, and circuit breakers for fault tolerance. We design communication patterns that match your consistency and latency needs.
What does proper actuator setup look like?
Health checks that verify real dependencies, not just application startup. Metrics exposed in formats your monitoring stack consumes. Info endpoints with build versions. Security configured so production endpoints aren’t publicly exposed.
How do you handle configuration across environments?
Externalized properties with Spring Cloud Config or environment variables, profile-specific overrides for dev/staging/prod, and secrets management through vaults or cloud-native solutions. Same artifact deploys everywhere.
Do you work with reactive Spring Boot?
Yes. WebFlux and reactive data access make sense for high-concurrency, I/O-bound workloads. For typical CRUD services, blocking MVC is simpler and sufficient. We recommend reactive when the use case actually benefits from it.
