Software Architecture Consulting
Solid technical foundations to support your growth, without mortgaging your future.
The architectural challenge
Poor architecture is invisible when things go well — and catastrophic when volume scales or the team grows. Technical debt accumulates silently until every new feature becomes a project in itself.
We help you build or refactor a robust, scalable software architecture adapted to your reality — not to a passing trend, but to your business context, your teams, and your actual constraints.
What we do
- Application architecture audits and code review
- REST, GraphQL and Event-Driven API design
- Data integrations: FDW, ETL, OpenData, real-time streams
- Multi-client and multi-tenant architecture
- Technical debt reduction and guided refactoring
- Application security, performance and scalability
- Cloud, on-premise and hybrid strategy
Architecture patterns we design
Every context is unique. Here are patterns we regularly implement for our clients.
REST API & API-first
A clear, versioned contract between frontend and backend. Documented with OpenAPI, secured by JWT. Ideal for exposing business logic to multiple types of consumers.
Multi-client & API Gateway
A single entry point for all consumers. Centralized authentication, rate limiting and routing to specialized backend services. Scales independently by service.
FDW — Foreign Data Wrapper
Federate heterogeneous data sources (PostgreSQL, MySQL, CSV files, APIs) into a unified SQL view. Cross-source queries without heavy ETL, with PostgreSQL-native permissions.
OpenData & Public Portals
Expose public or partner data through open standards (OGC, GeoJSON, JSON-LD). Fine-grained access governance, versioning, third-party consumption without friction.
Event-Driven & CQRS
Services decoupled via a message broker. Each domain publishes events consumed independently. Native audit trail, horizontal scalability, resilience to partial failures.
Hexagonal Architecture
Business domain at the center, isolated from all infrastructure. Adapters (REST, gRPC, JPA, Events) plug into ports without polluting application logic. Maximum testability.
Code Audit & Quality Metrics
Before designing the target architecture, we measure the real state of your codebase. Objectively. Without judgment.
Test Coverage
Line and branch coverage measured with JaCoCo or Istanbul. We identify critical zones with no tests and prioritize the testing strategy accordingly.
Cyclomatic Complexity
Methods with too many branches create maintenance nightmares and testing black holes. We spot and refactor them with measurable targets.
Technical Debt Index
Quantified in person-days via SQALE methodology. Code smells, duplications, security hotspots — we give you the total remediation cost estimate.
Coupling & Cohesion
Afferent/efferent coupling, instability index (Ce/Ca), package dependency analysis. Detect god classes and circular dependencies before they paralyze the team.
Security Hotspots
OWASP Top 10 automated scan: SQL injection, XSS, broken access control, cryptographic failures. CVE analysis of dependencies (OWASP Dependency Check).
Performance & Bottlenecks
N+1 query detection, missing indexes, slow endpoints, memory leaks. We profile the real stack in staging conditions and provide prioritized recommendations.
Audit deliverable
A comprehensive report with a dashboard of key indicators, a prioritized backlog of fixes, an estimated remediation effort, and a presentation session with your team.
- Executive summary (2 pages) for management
- Detailed technical report per module
- Prioritized action plan with effort estimates
- SonarQube project setup for continuous monitoring
Starting from 3 days for an initial audit
Request an auditOur approach
Audit & diagnosis
Review of the existing system: code, infrastructure, data flows, pain points identified with the technical team.
Target & recommendations
Documented target architecture, option comparison, explicit trade-offs. No single solution — multiple scenarios depending on constraints.
Migration plan
Pragmatic roadmap, no big bang. Breakdown into deliverable milestones, prioritization of quick wins and structural work.
Support & knowledge transfer
We stay alongside the team during implementation. Code reviews, pair programming, training on adopted patterns.
