System Integration and API Management

Designing, Implementing, and Securing APIs in the Spring Ecosystem

Isolated systems and inefficient APIs generate hidden costs, slow innovation, and create security vulnerabilities. Manual data exchange, a lack of consistency, and no central access management are a direct path to losing your competitive edge and violating compliance.

We help connect distributed applications into a cohesive, automated ecosystem. We design and implement secure REST APIs and complex integrations (EAI) based on Spring Boot and Spring Integration. The result? A reliable, scalable, and secure architecture that supports your business goals.

Key Benefits for Your Architecture

Our services address key technical and business challenges, helping your organization unlock the full potential of connected systems.

Increased Operational Efficiency

By automating data workflows and eliminating manual processes between key systems (e.g., CRM, ERP, e-commerce platforms, legacy systems).

Reinforced Data Security

Through centralized access management, implementation of OAuth 2.0 standards, and API traffic monitoring.

Greater Architectural Scalability

We enable the seamless addition of new services and systems without disrupting existing business processes and while maintaining high performance.

Faster Innovation (Time-to-Market)

Thanks to an API-First approach and clear, machine-readable OpenAPI documentation, teams can work in parallel, shortening the development cycle.

New Business and Partner Opportunities

By securely and controllably exposing data and functionalities externally (External API), you open your company to new partnership models.

Our Integration Service Scope

We provide comprehensive support at every stage - from architectural requirements analysis to implementation and maintenance.

Our scope of services includes:

REST API Development with Spring Boot

We design and implement efficient, semantically correct APIs (Spring REST). We focus on code cleanliness, optimization, and standards compliance, which guarantees ease of API consumption by other systems.

Liferay System Integrations

We have deep expertise in connecting external services and legacy systems with the Liferay ecosystem. We ensure a consistent user experience (SSO) and a secure, bi-directional flow of business data.

Authorization Mechanisms Implementation

We implement advanced security mechanisms. We design OAuth 2.0 flows, utilize JWT tokens, and integrate systems with identity servers like Keycloak, ensuring granular access control.

OpenAPI-Compliant API Documentation

Every API we create is delivered with precise technical documentation compliant with the OpenAPI (Swagger) standard. This facilitates developer onboarding, accelerates testing, and provides a clear, machine-readable communication contract.

How we work

Our implementation process

Implementing a stable and secure integration requires a methodical process that minimizes risk and maximizes value for your architecture.

1. Analysis

We identify source and target systems. We map data flows and business processes for automation. We define non-functional requirements (performance, security, SLAs).

2. Planning & Architecture Design

We design the target integration architecture, selecting appropriate EAI patterns. We define API contracts (OpenAPI) and design the security model (authorization, OAuth 2.0 flows).

3. Implementation

We develop the API code and integration logic using Spring technologies (REST, Integration). We implement security mechanisms and configure connections between systems.

4. Testing

We verify the solution's functionality through unit, integration, and performance testing. We ensure the business logic is implemented correctly and the system is fault-tolerant.

5. Deployment

We deploy the solution to the target environment (staging, production). We configure monitoring, logging, and alerts to ensure full observability of the components.

6. Knowledge Transfer & Documentation

We deliver the complete source code with full ownership rights, interactive OpenAPI documentation, and architectural documentation. We support your team in the maintenance handover process.

Technologies we work with

Our Integration Technology Stack
