You've probably used products built by our Spring Boot developers.
We've built Spring Boot systems across industries, from customer-facing applications to high-throughput backend services and large-scale integrations. Work with engineers who've already solved your hardest problems.
Monolithic applications slow delivery and limit team autonomy. We build Spring Boot web applications using Spring MVC or Spring WebFlux that handle complex business logic, integrate with legacy systems, and scale horizontally as traffic grows. Our implementations separate concerns through layered architecture, use Spring Data for persistence, and expose REST APIs for frontend consumption. Your teams ship features faster while maintaining code quality that survives years of iteration.
Moving a core monolith to microservices changes the behavior of your entire platform. We design distributed systems with Spring Boot and Spring Cloud that handle service discovery, resiliency, and centralized configuration. Our microservices run in containers orchestrated by Kubernetes, communicate via synchronous APIs or messaging, and apply proven patterns to maintain data consistency across services. Your architecture gains the independence to scale services separately and deploy updates without system-wide outages.
APIs must remain stable as systems evolve. We design and build APIs with Spring Boot, most often RESTful but including asynchronous and event-driven patterns where they make sense. Our implementations handle authentication through Spring Security, rate limit to protect resources, and provide clear error responses. External partners and internal teams get reliable integration points that don't break with every release.
Legacy Spring applications accumulate configuration complexity and security debt. We migrate traditional Spring applications to Spring Boot, replacing XML configurations with annotation-based setup, updating deprecated dependencies, and refactoring to leverage auto-configuration. Our process includes parallel testing environments, incremental rollouts, and documentation that explains architectural decisions. You gain modern infrastructure that’s easier to maintain, monitor, and extend over time.
Authentication and authorization failures create compliance risk and security breaches. We implement Spring Security configurations that integrate with OAuth2 providers, enforce role-based access controls, and protect endpoints through method-level security annotations. Our implementations handle JWT token management, session security, and CSRF protection while maintaining audit trails. So your applications meet security requirements without forcing users through cumbersome authentication flows.
Data access layers bloat with repetitive code and N+1 query problems. We implement Spring Data JPA and Spring Data JDBC that abstract persistence logic, optimize query performance, and handle transactions consistently. Our data layers support multiple databases when needed, implement caching strategies with Redis or Hazelcast, and use database migrations with Flyway or Liquibase. Teams ship features without rebuilding the data layer every time, while keeping fine-grained control over queries and indexes.
Cloud platforms offer elasticity that traditional deployments can't match. We build cloud-native Spring Boot applications for AWS, Azure, or GCP that leverage managed services for databases, messaging, and caching. Our implementations use Spring Cloud for service mesh patterns, externalize configuration to reduce container rebuilds, and instrument with distributed tracing. Your applications scale automatically with demand and integrate cleanly with cloud-native tooling.
